Please allow for "Fixed" locations for delete and other buttons

[jrconlin]

When going through my email, I often encounter individual messages and message threads. These two different message types have different button bars displayed. I often review my mail in a session, and it would be very useful if I could keep my mouse in the same location to quickly delete either.

As it is, I may be deleting a large number of single emails, but then accidentally archive a mail thread I did not intend because the button shifted.

Ah, it is! Thanks. 
I'm fine with closing this idea in favor of that one.
