[TxMt] Testmate 2: File browser navigation bar

Can I please suggest we have the option to position the navigation bar in the file browser at the bottom? Aesthetically, I think this would look much better, besides being what I'm used to in TM1. I will never use the backwards and forwards buttons, because I open other projects in a new TM window. If I did traverse multiple projects/files in the one TM session, I could see how having the nab bar at the top would make sense; but since there is no way to tell which folder an open file belongs to except by floating over the tab, it makes it quite confusing.

Also the icons in the navigation bar the final version? I find them a little fuzzy.
