Lego Like windows

While compiling in Konosle today - I had an idea. This sort of goes along with what is already on the plasma web site with the detachable reminders. It would be very nice to be able to hook together or nest different application windows together. My example is konsole with the performance monitors of Ksysgaurd. That way you could compile and watch cpu level, or freq, or whatever.

Othere uses could be inside koffice - you could have a nested widget to check an online dictionary while still in your writing app.

Putting an amarok corner win konqueror while web browsing.

This might be easier to implement as most programs having features that can be reduced to a sidebar, and then being able to attach that sidebar (Borderless?) to another program.

Some of this could boil down to simple customization options, but I think there is great potential for usability and extended functionality here.
