"Nothing to tag" button UX changes

Current Behavior

Experiments with users resulted in complaints about the "Nothing to tag" button being hard to find.

Expected Behavior

This button should be visible for users without any problems. We need to find some suitable place in visible area of interface and place it there.

Also, let's change the name to something more descriptive 😉 "Nothing to tag" seems to be unintuitive.
