Thanks a lot for all your positive feedback!

Hmm... I don't know if this is a good idea. And sadly I have moreover no clue how to monitor text selections at other applications.
So perhaps this is not a realizable feature. Sorry.

Good Idea. Hmm... perhaps you could check in the meantime the Application Quick Launch if this could do the trick for you without using the keyboard.
If you run ClipMan after you have copied something to the clipboard it get's also grabbed and stored. So perhaps this could work very handy.

A feature to keep this thing running without constantly opened clipman window is planned. I hope to get something like this working soon.

But first I would like to port the current state of this application to MeeGo and then continue to develop ClipMan across Maemo N900 and MeeGo Handset / Tablet at the same time. I guess I will have some more troubles because of the differences between Maemo and MeeGo targets as soon as I've integrated such a background daemon. So I would like to port this application as long as it is as simple as currently.
My plans regarding MeeGo are currently in a very early state. I've troubles to setup a consistent developing environment for all three targets. So please don't count on this feature within the next weeks. But this feature is planned. Don't worry.

Until I have a simple solution for this I'm following a small learning project to prepare myself to develop a small game. So the development of ClipMan gets slowed down a bit...

If you're able to give me some spare time, donations are welcome.
