Tips & Tricks

The list of accounts and contacts fits into one window. When starting a conversation a new window pops up. Keyboard integrations works flawlessly. It's not suggested to have two open conversations at the same time in that second window (just close the conversations except one, the messages won't disappear though).

Known Issues:

New messages doesn't always appear in the top line of phosh.
