Currently we display account information only once we open a chat. It would be convenient if it would be possible to know to which account chat belongs without opening the chat. One idea would be to add option to define account colour and display it as 5-10px border on the left side of the chat item in the list.

Idea comes from k9mail, tho in recent version it is reduced to small chip (https://docs.k9mail.app/en/6.400/reading/unified_inbox/)
