I am using Memeclip Pro for the moment but it isn't helping much. It's even buggy from time to time so I'm looking forward to see this utility in my systray.
A feature that I haven't find in any copy paste program (or in general) are those presented in this little gem :
1 Keyboard focus follows mouse pointer instantly (the only one that can be achieved with TweakUI, annoyingly enough accompanied by the "quality" to raise the window upon click).
2 Marked text is placed into the paste buffer instantly on left button release.
3 Pasting is done with a single middle button click. (The latter two are implemented in couple of applications - only to feel more acutely the lack of it in the rest of the windows!)
But it has bugs too and I can't have it running all time. Can you take a look at this program and see if you can incorporate some if its features?
The ability to quickly copy paste information between 2 windows increases drastically. Just select with 1 click, go to the other window and use middle mouse button.
Contrast this If TXMouse is not running. Select the text,Ctrl-C, click on the target window,Put you cursor at the desired position,Ctrl-V,activate the source window.
Thats 2 clicks vs 4 clicks/2 keyboard actions.
I am not yet a paying member but CHS looks very promising!
