New Plugin : Retrograde
Some time ago I made a very simple retrograde plugin. Basically, you select some notes and it will create a new score with the same notes in the reverse order. You can them copy paste the result where you want.
Apparently, it's useful. So I just created a dedicated page for this plugin : http://musescore.org/en/project/retrograde

I used this way back with 1.1. Is there any chance it can be updated for use with 2.2.1. It was a handy tool. (wish I knew how to code)
