After working on a sermon all morning, I had an idea I thought I would suggest.
Sometimes after you've been studying for several hours your workspace gets cluttered and you need to clear out certain tab groupings, but you want to retain a certain group of tabs. That means that right now we right click and then click "close all tabs." While this is fairly quick, it would be nice if we could have a shortcut to accomplish the same task. My idea would be to allow the user to "close all tabs" by clicking on the "x" while holding down the ctrl or shift key.
This would allow the user who is looking to close many tab groupings "at a glance" to quickly and efficiently close many groupings. Sometimes when you are trying to close things up quickly you click on "close this tab" or "close others" by accident, and thus end up having to go through the menu again more carefully. If you enabled a shortcut for "close all tabs," it would reduce my clicking by as much as 5-10 clicks when I have really flooded [:P] my screen over the course of a study.
