Dragging moves all selected notes, or does here anyway.....
Pre X1 there was no smart tool as such. The PRV had a multi tool but it didn't auto adapt to differnet views like this new tool, hence the term 'smart'.
There's now no need to change tool except on the odd occasion. I appreciate that users have different ways of working but the only time I select a different tool now is the mute tool for comping with.
YMMV of course.
