The first version of quick compose skipped `onBeforeCompose`, a composer
moved back could end up open in both windows, a reply moved back under
Pro flagged the selected message, and a crashed pop-out came back blank.
- A new message in a pop-out runs `onBeforeCompose` with the same result
as the main window: a plugin that stops it closes the window.
- The way back has two steps, so a pop-out that gave up can't leave a
second owner. A handoff behind a plugin's gate makes it say busy.
- A Pro tab made from a composer moved back answers its own message.
- Each save writes `draft`, `account` and `owner` into the pop-out's
address, which a reload after a crash starts from. What was typed since
the last save, up to the 2 s autosave delay, is still lost.
- The recorder refuses keys that type a character on this keyboard, and
what the shell refuses from a page, and says why.
A restored composer opened whatever the id named. Sending keeps the id, so its autosave would have destroyed the Sent copy, Send mailed it twice and Discard deleted it. It now needs the login in its address and a real draft, keeps its From with several accounts, and stays on the list if the server doesn't answer. A message from a bulwark:// link no longer marks itself read or sends a receipt. Native menus speak all 30 languages. Spellcheck dictionaries come from Google only after a yes, never in no-third-party mode.
