thanks for the feedback.

The dock & menu bar issue can be easily solved by redownloading the 
update.

Selecting the iTunes® Behaviour as default in the Preferences should 
also always start up iTunes. To fix the problem, click on 
"Advanced.." in the Preferences and select "None (recommended)". 
iTunes should no longer start on Remote Buddy startup then.

Regarding your feature request: this functionality is already around 
for a few releases as part of the menu. I plan to make it accessible 
as mappable actions in a future release as well.

Best regards, 
Felix
