The blue Share button at the top of Adobe Standard DC is not something I use regularly and it takes up a lot of space. There are toolbar tools that I use more often. I want to move it off the main tool bar area,. It's not part of any of the toolbars.
There was another question on this (which is marked as answered) but the answer provided was just showing an alternate way to send files via email. It was not answer to the question of how to move this (large) button off the screen.
