Issue #3 resolved
Select a tweet in the timeline, then deselect it. No tweets should be selected.
Click on a user's name in the timeline to see their profile information.
Click on the "home" icon to return to your home timeline.
What I see: the tweet you had selected/deselected in step 1 is now re-selected in the home timeline.
What I expect: nothing in the timeline should be selected and I should be back at the top of the home timeline.
