Improvements to floating action toolbar

[annezazu]

What follows are some tasks to improve the action bar experience. While there's broader discussion around keeping this action bar in the long run, there are also plenty of tasks to improve it in the short term. I created this from current known issues. cc @jordesign @inaikem for any additional items you can add from users or your own walkthroughs here. @davemart-in as I know you have lots of thoughts and experience here!
