Adding a search bar to the channel selection screen in Mail & Activity (and on boards) would make it much easier to find the right channel.

Description

When composing an email in the Mail & Activity app, the sender needs to select a channel from the dropdown list.
With many channels registered, it can be difficult to quickly find the right one.

It would be very helpful if a search bar could be added to the channel selection screen.
We believe the same improvement could also apply to the channel selection screen on the board.

What are you trying to achieve

We want to make it easier and faster for users to find the right channel when composing an email or selecting a channel on the board.
