vi with mouse integration? They have had this for years. Download the source and grok my friend. You probably are running nvi and not vim. Also in either your terminal or x you can simply middle click your mouse if you need to mouse copy/paste. I recommend addressing in ex mode or using the vi visual mode commands to do it. If your really dependent on "drag/drop" gui style editing using ex proper will defeat that. In vim I'm sure a simple script would even bring it to the gui drag/drop concept to the editor by automating addressing from mouse selection. Though it would be slower for the end user and simply not provide the flow and control ed and vi/ex users have had for years.
