Just a little-known feature...

Not everyone knows about this (my fault for lack of documentation!) but you can detach channel tabs and DCC tabs from the main client window. Just right click on the tab and choose detach. To reattach, click the little arrow in the window title.

Each channel window should remember its size and position, so you can arrange them on your desktop however you'd like.
