I wanted to use Scaler to develop material in an existing track at bar 64. If I highlight some chords and attempt to drag them there, there is no autoscrolling at the window edge. The only way to get them there is drop them at the max of the SC window which is around 16 bars visible (but the drop has to be done around 13 bars otherwise it reverts to the original position, then scroll, then drag, then drop, then scroll etc. Thats boring!
Nor do any of the wheels on my mouse control anything although there are scroll bars in the interface. That would be really handy too!
How about an additional selection option. A common Mac option is to holding Alt while selecting the beginning of a range, then select the end of a range which highlights the whole range. Thats perfect for long strings of chords and can be faster than finding the dragging sweet spot or using Command Select to choose the range one by one..
