I have been testing out DO & WOW!
I was wondering if DO has a function similar to xplorer2 "Mini Scrap". I've been playing around with it and find it quite useful.
Basically you can drag files or folders from anywhere into a small windows and then copy/move... the group of files. It is pretty slick.
It sounds like File Collections are what you're looking for.
The Scrap Collection Toolbar may also be of interest. (It gives you a button to send things to a "scrap" file Collection without having to view the collection, and that type of thing.)
Scrap Collection Toolbar works nicely.
Might be nice to add this functionality in DO 11....
The toolbar works in Opus 11 just the same as it did in Opus 10.
