 ## [Unreleased]
 
+## [0.8.1] - 2026-10-02
+
+### Added
+
+- Non-ASCII search terms also work on servers that advertise `LITERAL-` instead of `LITERAL+`, such as Gmail, for terms up to 4096 bytes
+
+### Changed
+
+- Non-ASCII folder names are shown decoded (`[Gmail]/Messages envoyés` instead of `[Gmail]/Messages envoy&AOk-s`), and folder options and config settings accept either form; `--json` output and `export` file names use the server's listed name (so `--folder inbox` exports `INBOX_<uid>.eml`)
+- `--limit` fetches headers only for recent matches when they suffice instead of for every match, on servers without SORT, such as Gmail, and in each folder of `--all-folders` on every server (`search --limit 5` on a 7,480-message Gmail INBOX: 22.9 s to 1.6 s)
+- On Proton Mail Bridge, `--all-folders` skips the label views (`Labels/...` and `Starred`), so a labelled message is listed and counted once, from its regular folder (on a 150,000-message account, `search --all-folders --limit 5` went from 33.9 s to 3.1 s and the `count --all-folders` total from 305,131 to 151,285)
+
+### Fixed
+
+- `--all-folders` and `status` skip containers that cannot be opened (`\Noselect`, such as Gmail's `[Gmail]`) instead of warning about or listing them
+- On Gmail, `--all-folders` lists a message once even when it has several labels (the INBOX copy if there is one), and actions apply to that copy; `count --all-folders` totals count it once
+- `--all-folders` also skips folders inside Trash, Spam/Junk, and All Mail (such as `[Gmail]/Trash/Old`)
+- When slashmail orders messages itself (servers without SORT, `--all-folders`, `--all-accounts`), a Date header more than a day after a message arrived counts as arrival plus one day, so a wrong or forged future date no longer pins a message to the top or pushes newer messages out of a `--limit`

+On Gmail, where every label is a folder, `--all-folders` lists a message once even when it has several labels: the INBOX copy if there is one, otherwise the copy in the first folder listed. `read`, `export`, `mark`, `move`, and `delete` act on that copy. `count --all-folders` still shows each folder's own count, but its total counts each message once.
+
+On Proton Mail Bridge, every message sits in exactly one regular folder (INBOX, Archive, Sent, `Folders/...`), and its `Labels/...` folders and `Starred` are views of those messages. `--all-folders` skips those views there, so each message is listed and counted once, from its regular folder.

+Servers list non-ASCII folder names in IMAP's modified UTF-7 (`[Gmail]/Messages envoy&AOk-s`). The terminal shows them decoded (`[Gmail]/Messages envoyés`), and every folder option and config setting accepts either form. `--json` output keeps the server's form.
 
 ### Action options
 
@@ -305,11 +311,11 @@ Commands that modify messages (`delete`, `move`, `mark`) support:
 
 `delete` and `move` require the server to advertise `MOVE` or `UIDPLUS`. Without `MOVE`, messages are copied, flagged `\Deleted`, and removed with `UID EXPUNGE` of exactly those UIDs; other messages already flagged `\Deleted` are never expunged. This fallback is not atomic: if a step fails, slashmail stops and reports it without retrying, including how many messages were already moved or updated. Every mutating command and `export`/`read` refuse to act if the folder's `UIDVALIDITY` changed since the search. Immediately before `delete`, `move`, and `mark` act, slashmail asks the server which searched messages still exist; their receipts count only those and report any another client removed in the meantime.
 
-`export` supports `--yes`, `--force` (replace existing files), and `-o, --output-dir`. Files are named `<folder>_<uid>.eml`, where the folder name is percent-encoded: ASCII letters, digits, and `-` are kept and every other byte becomes `%XX` (so on Linux and macOS `Work/Projects` is `Work%2FProjects_1.eml` and `Work_Projects` is `Work%5FProjects_1.eml`). On Windows, lowercase letters are also encoded so folders differing only by case stay distinct (`Work/P` is `W%6F%72%6B%2FP_1.eml`). Without `--force`, an existing file is skipped only when it already holds the same message (identical bytes or the same Message-ID). UIDs restart when a mailbox is recreated or migrated, so an existing file holding a different message is left unchanged and reported as an error after the other messages are exported; use `--force` or a new output directory. `--force` replaces only a regular file or symlink entry and never follows symlinks. New exports and saved attachments are created owner-only (`0600`) on Unix.

+Search terms containing non-ASCII text are sent as UTF-8 literals and require the server to advertise `LITERAL+`, or `LITERAL-` (as Gmail does) for terms up to 4096 bytes; otherwise the search fails before any mailbox is searched. Proton Mail Bridge advertises neither, so non-ASCII search fails there. Bridge also matches `--subject` and `--text` against the raw message as stored, so words inside an encoded subject (common when it has non-ASCII characters, often base64) may not match, accented or not. To find such messages there, narrow with other filters (`--from`, `--since`) and check the decoded `subject` in `search --json`.

 ## How it works
 
 - All filtering runs server-side via IMAP SEARCH
-- Uses IMAP SORT extension (RFC 5256) when available; falls back to client-side sort
-- With SORT, `--limit` truncates results before fetching (fewer bytes over the wire)
-- `search`, `delete`, `move`, `mark`, `count` only fetch headers and size -- never full messages
+- Uses IMAP SORT extension (RFC 5256) when available for a single folder. Otherwise, and for every folder of `--all-folders` and every account of `--all-accounts`, slashmail orders by the Date header, but never later than one day after a message arrived, so a wrong or forged future date cannot keep a message at the top
+- `--limit` keeps header fetches small. With SORT, a single-folder search is truncated before fetching. Otherwise (no SORT, as on Gmail and Proton Bridge, and each folder or account being merged), a large search is first narrowed to recently arrived messages with `SINCE`, and every match is fetched only when those hold too few. The result is the same as fetching everything
+- `search`, `delete`, `move`, `mark` only fetch headers and size -- never full messages; `count` fetches neither (only message IDs with `--all-folders` on Gmail)
 - `export` fetches full message bodies via `BODY.PEEK[]`
 - Uses `BODY.PEEK` to avoid marking messages as read, and opens folders read-only (`EXAMINE`) for `search`, `read`, `count`, `export`, and `--dry-run`, so they do not clear the `\Recent` flag
 - UID sets are compressed into ranges and chunked to stay within IMAP command length limits

 ### Folder not found
 
 - Run `slashmail status` to list all available folders and their names
-- Folder names are case-sensitive on most IMAP servers
+- `search`, `read`, `export`, `mark`, `move`, and `delete` need a name `slashmail status` lists, decoded as shown or as the server sends it (INBOX in any letter case). `count`, `reply`, and `attachments` also try a name exactly as typed, for mailboxes a server opens but does not list
 - Gmail uses `[Gmail]/Trash`, `[Gmail]/All Mail`, etc. — use `--trash-folder` with `delete` if needed
 - Exchange/Outlook uses `Deleted Items` instead of `Trash`

 - Never pass an empty text filter (for example an unset variable as `--from`); slashmail rejects it rather than matching every message.

+- With `--all-folders`, a Gmail message with several labels is one row, from INBOX when it is there, and commands act on that copy.

On Proton Bridge, label folders are skipped: to work with a label, name it with `--folder` (for example `--folder "Labels/Clients"`).
+- On Proton Bridge, server search cannot see words inside an encoded subject (common when it has non-ASCII characters): `--subject` and `--text` both match the raw message.
