Thanks for bringing renoise to OS X! 
A feature I would like to see is multiple screen support. I have a Powerbook 12" that I use for renoise but when at home connect to a second monitor. It would be handy for renoise to have windows that could be broken apart so that the sample editor could be moved off to another screen and elminate writing down offset locations on paper. Don’t get me wrong I actually prefer the one screen does it all interface. But if there were an option to turn on break apart modules in the prefs it would be pretty rad. If not break apart then maybe the capability to launch a carbon copy of the current interface (view 1, view 2 etc) that could be modified to show different controls and achieve the same goal. Thanks again!
Good Idea, but I think the current GUI-programming does not allow such a feature.
