Order applications alphabetically in drop-down list when grouped together

[peeterm007]

Hello and thanks for a great app!

I wonder if it's possible to have applications ordered alphabetically in the drop-down list when one left clicks on the button where windows are grouped? This is relevant when there are many, say, pdf documents open and I have grouped windows under one button. When I left click, a list with all those pdf-s is created, and it would easier to find the right one if the list was ordered alphabetically. I noticed that Mac OS has this feature, it makes easier to navigate between open pdf docs when there are lots of the pdfs open. I wonder how difficult it would be implement something like this?

Thanks
