change display of repository's tab close button
Currently tab's close button is very big and has small padding from the left between the text and the button and large padding from the right. Its not very user friendly and a lot of accidental close button clicks happen. Current view on windows:
I propose that it would be pushed to the far right and close button would be displayed only on active tab like in mozilla firefox and make it smaller leaving just an x mark. If you hover on it it appears bigger as square is added grey or red:
this would save some space and would be more comfortable. Note that you can always close inactive tab with a middle mouse button click.
