With this dialog you can hide ( or show if hidden ) Channels , @Windows and Query windows. You can hide/show one at a time or all at once.

Edit 13Aug08: It will now join you to the channel you double click ( hidden or not hidden ) , make the Query and the @Window your active window ( hidden or not ) which will make them no longer hidden and resetting the Visible / Hidden list as needed.

Edit 13Aug08: Added a script that if a channel/query is hidden and some one speaks in the channel/query it will then be the active window. If something is entered into the @Window it will reappear minimized in the channels list.

Original base script and idea from ch1zra
