+- The text on the plan sheet is sharper - it is drawn with ClearType like the rest of the window.
+  The sheet's shadow looks the same, but it no longer makes the whole sheet redraw with every blink
+  of the cursor. Where the window is drawn without the graphics card, as it is over Remote Desktop,
+  that cost a third to half of a processor core for as long as the box a name is typed into was
+  waiting.
+- A plan with more than twenty commands shows them in one field that can be selected and copied,
+  instead of a box and a Copy button for every line. *Copy all* still takes all of them. The same
+  goes for the way back after a run. A plan over a whole scope opens noticeably faster.
+- When a plan touches several entries this machine does not work without, the sheet names them all
+  in one sentence instead of one sentence each. On a plan over a whole scope those sentences used
+  to push every step off the sheet.

+        redraw of anything inside it - the caret in the confirmation box, the progress line once a
+        second - had WPF blur the sheet again. Where WPF draws in software, which is the case over
+        Remote Desktop unless an application opts out, that was a third to a half of a core for as
+        long as the confirmation box held the keyboard, and 8-14% of one through a run. As a
+        sibling under the sheet it cost nothing measurable over no shadow at all in either mode:
+        WPF blurs again when what is UNDER the effect changes, not when something drawn over it
+        does - the prediction said otherwise and the third run settled it. A bitmap cache round the
+        effect added nothing measurable and drew the shadow further from the shipped one.
+
+        AND THE SHEET'S TEXT GOT ITS ClearType BACK, which is the visible half. An effect turns
+        ClearType off for everything under it - measured on the 16 826 pixels of the sheet's text
