It does what it needs to
I really like the website but the app could be improved in a couple of ways to get 5 stars from me:
-Ive ticked the "keep me logged in" box on the login page but I often still find myself needing to enter my password (which I usually forget because I have so many I cant keep track)
-after logging in, it takes a very long time (like 30 seconds) for the activity stream to refresh. That might not seem like a lot on paper, but when youre trying to be productive it feels like an eternity.
This is all I can think of right now; aside from these Im pretty content with everything else.
