In the few minutes I've played with Groupy, I really love it. Now I can discontinue using Office Tab which has been a bit kinky with the Microsoft Office 365 applications like Word and Excel it was made for.
But there is one key feature absent from Groupy (unless I'm missing something, which is always a possibility):
A single button to close all of the files that are open in a "group." Now I can understand lacking that ability if the group is comprised of windows from several different programs. But when all of the open files are in the same program (like Word), would it be possible for Stardock to add a button to Groupy to close all of the documents in that group?
