I'd almost be tempted to make this a <template> we could pull out and instantiate, but this isn't so hairy yet that it feels urgent 😅

const s = getSavedQueries();
for (let i = 0; i < s.length; i++) {
const entry = s[i];
const li = document.createElement('li');
const name = document.createElement('span');
name.className = 'query-name';
name.textContent = entry.name + ':';
const span = document.createElement('span');
span.className = 'query-text';
span.textContent = entry.query;
span.title = entry.query;
const del = document.createElement('button');
del.className = 'delete-btn';
del.textContent = '\u00d7';
del.title = 'Delete saved query';
del.addEventListener('click', (evt) => {
evt.stopPropagation();
const cur = getSavedQueries();
cur.splice(i, 1);
setSavedQueries(cur);
renderSavedQueries();
});
li.appendChild(name);
li.appendChild(span);
li.appendChild(del);
li.addEventListener('click', () => {
query.value = entry.query;
query.focus();
});
savedList.appendChild(li);
}
}

function recordHistory() {
const errorDiv = document.getElementById('error');
const q = query.value.trim();
if (!q || errorDiv || !output) return;

const h = getHistory().filter(e => e.query !== q);
h.unshift({ query: q, source: sources.value, ts: Date.now() });
if (h.length > MAX_HISTORY_ENTRIES) h.length = MAX_HISTORY_ENTRIES;
setHistory(h);
}

saveButton.addEventListener('click', (evt) => {
evt.preventDefault();
const q = query.value.trim();
if (!q) return;
const name = prompt('Name for this query:');
if (!name) return;
const s = getSavedQueries();
s.push({ query: q, name: name.trim() });
setSavedQueries(s);
renderSavedQueries();
});

clearHistory.addEventListener('click', (evt) => {
evt.stopPropagation();
localStorage.removeItem(LOCALSTORAGE_KEY_HISTORY);
renderHistory();
});

// Disable the download button when there are no query results.
window.addEventListener("load", disableIfNoOutput(dlButton));
// Initially focus the query input.
window.addEventListener("load", (evt) => { query.focus(); });
// Refresh when the input source changes.
sources.addEventListener('change', (evt) => { qform.submit() });

// Persist open/closed state of query panels across page reloads.

Nice

document.querySelectorAll('#query-panels details').forEach((d) => {
if (localStorage.getItem(d.id) === 'open') d.open = true;
d.addEventListener('toggle', () => {
if (d.open) localStorage.setItem(d.id, 'open');
else localStorage.removeItem(d.id);
});
