How about one "Select/Move" window where you can select the various start and end points of a selection on a track (as in the Block menu) with an option to Cut or Copy and Paste the contents of that selection.

Then enter the destination start and end point along with all the options as shown in the Paste window and also the Track # to paste selection to another track.

Also include a Move option box to enter just the number of Beats and Ticks to move the selection left- or right+ on the destination or original track.

Combining all these options in one window could greatly simplify the fine tuning workflow.
