Hi BlackWinny, thanks for your comment! I have just fixed the bug about the tab always being closed and released a new version (0.1.3).
Thank you for your suggestions as well. Regarding the first one, the text field should get the input focus automatically, at least it does in Chrome, I'll have to debug it in Firefox.
I'll think about your second suggestion as well. I added the name of the parent folder but certainly it may induce to error. Having some kind of tooltip with the full path when hovering would certainly be useful.
