Modifier Drag&Drop
**Warning: WIP!** Basic functionality works fine and there shouldn't be any
crashes, however, if you occur issues, feel free to report them to me (not in
the bug tracker!)
Some more effort is needed to get this ready for master, but I thought it would
be nice as a little present for the Gooseberry-team (I heard some of you were
requesting this?) and the ones using the Gooseberry-builds :)
Oh, and better not look at that code, it's ugly and a lot of changes are
planned, I just wanted to get something working before getting into details.
