Using CTRL+C or copy a lot? Try out new ENSO+ command "watch selections".
It monitors your activity and every time you make selection it adds it as line to queue. It grabs all text you copy also. Later you can easily find that text you worked with and paste it at new place. That way you don't have to switch windows so many times when working with same set of text. People like programmers or text editors could find it useful.
At the moment it monitors selections you make with mouse by dragging over text or by double-clicking or by using CTRL+A. And pasting already added text can be done by dragging it out from queue, double-clicking it in queue or by using key combination assigned by command "assign key combination for paste operation".
Don't worry - your clipboard is not messed up.
