Better.

However, I suggest that showing help should quit window editing. The reason
is that you are in a `read-event' loop, and that prevents any normal
interactions with the help. For instance, you cannot resize the help frame
or scroll its window - all keystrokes (including mouse actions) are trapped
by the `read-event' loop. It is not difficult for a user to start
window-editing again, after help quits editing.

See above. It is a mistake, IMO, to not exit the `read-event' loop when the
help is shown.

Also, please don't turn off the cursor in the help window.

Suggestion: Put key descriptions in a single column, instead of having lines
that are up to 90 chars wide.

You can also shorten some of the descriptions, for readability:

- "toggle mode: move border, resize"
- "C-f, C-b, C-n, C-p: move cursor"
- "quit"
- "save window configuration"
- "move border" (singular, and get rid of "direction-wise")
- "select adjacent window" ("select" not "find", and "other window" means
something different)

Among other reasons, it's important to be able to undo an accidental
restore - this provides that.

HTH.
