I really agree about the clutteredness. I don’t need to see the little avatars for every team. Or Team Conversations (that’s what Slack is for) or Team Calendar (that’s what our calendar is for). Or, well, a whole lot.
That’s why I made this: Asana • simplified and with more hierarchy | Userstyles.org
Here’s what my Asana looks like right now: http://cozy.es/ErdfL2
(I also used Epichrome to turn Asana into an app, but that’s gravy.)
