Press, buzz or multiple bounce roll...

Hi, I would suggest the introduction of the notation for the above type of drum roll, it's like a "z" in the middle of the stem (same position as tremolos), you can see how it looks like by having a look at the fourth rudiment here:

Another thing that would be really useful to write rudimental drum parts without going crazy, is the ability to correctly flip articulations (already reported here: http://musescore.org/en/node/14472), because having to move each accent by hands is not practical, nor feasible for long parts.

Best regards and congratulations, because I think that this software is really good!
