When auto-expanding a pane and showing it as an overlay because of
narrow window, make the chat keep the width it had before.
This makes the transition less jarring, reduces the amount of text seen
through a transparent pane, and fix making one pane overlay expanding
the other.
If the room pane is below the default width (by user resizing or because
of narrow window), go to the room settings or a member profile will
automatically expand it as needed.
The pane goes back to its previous size once the settings/profile is
left.
If the window is narrow enough that expanding the pane normally would
reduce the timeline's width past its minimum, the pane is shown as an
overlay instead.
The attributes by mistake used nio.AsyncClient.user instead of the
proper user_id. If the user logged in with a partial username instead of
typing their full ID, the can_ attributes (e.g. can_kick) would always
be False.
The Timeline EventList is the only HListView that uses it. For other
list views, it interferes with items like text fields which need to set
cursor shape by themselves.
- Rename ButtonLayout module to just Buttons
- Rename ButtonLayout into AutoDirectionLayout and move it to Base,
it's useful not just for buttons
- Rename OtherButton into GroupButton, which is now the base of all
other Buttons buttons
- Add generic (Positive|Middle|Negative)Button components, which are now
the base for (Apply|Cancel)Button
If the account passed to `saved_accounts.update()` doesn't exist in the
config file, return instead of failing with a KeyError.
An account can be absent from the file if "Remember my account" was
unchecked on login, or if the file hasn't been updated yet on disk after
login (race condition).
