This is looking like a cool PR! I really like this feature, and the code (at least the front-end which I'm responsible for), is looking good.

However, I am having an issue where I am not able to load my previously created teams when checking out your PR in circles, is this something others are also experiencing?

@nfebe Hey! What do you think of this? You maintain the frontend for circles right?

I haven't anything like that. What error do you have? Please provide more detals, e.g. logs, screenshoots, etc

Rebased PR, BTW.
