I created few teams but I do not like the order which they show up
Is there a way to, for example, have "Gitlab" show before "Personal Boards"
At the moment there's no native functionality to reorder teams. That would be nice.
But there's a somewhat crude workaround. You can use Unicode emoji characters as the prefix of a team name and that'll put your team in different positions on your boards page.
You'll notice the positions are different on the web vs. mobile. On the web my emoji prefixed team names show up on the top. On mobile, those teams show at the bottom.
Team names in drop down lists are ordered alphabetically, and are not keyboard friendly. You can't type the first character to jump to it.
