Something I've wanted in CW/Sonar for a long long time is the ability to arrange and re-arrange parts of a song in an easy way by using what Reaper calls regions (not the same as regions in CW), or some kind of playlist where you can move around verse, chorus, bridge and other parts of the song witout needing to copy, cut and paste individual tracks.
Studio One also have this feature, and also Cubase? Reason too I think?
It is a very nifty tool when writing and arranging a songs basic structure. Some early sequncers had a pattern based way of building songs, and even if that may explain the feature I'm looking for, it is important that you can work in a linear mode at the same time.
EDIT: SO happy this feature now is a part of Cakewalk! great job!
Oh! And one thing that would be great is to be able to start a song from bar 0.0.0 as a count-in section.
