"If you hover over certain media files the file browser closes and there is a small notice that it is opening the file in caja. There are no controls and it is just annoying. I am going to be removing it. Often when working with two panes moving files it is just a pain when it does that. I can't imagine why someone would actually design it to do that. The old way of hovering over a media file and playing a preview without interupting whatever you were doing was fine. You move the mouse and it would stop playing. This way just seems too buggy to me."
