Closing all tabs quickly!

Closing all tabs quickly!

Hi,

I wanted to throw out an idea for a small quality-of-life change. One small issue that I run into regularly is that if I have many tabs open, it becomes sort of a pain to close them all quickly because even on the left-most email tab, the "x" button on the tab changes position as the width of the tabs increases to fill the horizontal space.  What would be really great is if there was a close tab button in the set of buttons at the top right of an email pane (e.g. next to the "Next Mail" and "Previous Mail" buttons) such that I can put my mouse over that one spot and just click a bunch of times to close all the tabs.  I hope that makes sense!  Another option would be a close-all-tabs button somewhere. I know there are keyboard shortcuts to control tabs, and I do use them occasionally, but a consistently-positioned close-tab button or a single way to close all tab on the UI would be even better, in my opinion!

Thanks!

Eric
