Is it like how mIRC contains the channel windows in the main window?
Actualy arn't panels different from a frame/group box ?
I know they're not exactly the same, frames can have captions and generally have a lot more functionality than panels, its the closet thing we have to them though and I was looking for something to relate them to.
@MrSak: Create a few and play around with them, they're not that hard to figure out.
