What do you mean for favourite channels? how? and which one (top or side)?
Looks like only one is possible, by using the -lN switch. anyway, Picwin experts can create anything
Never heard of Picwin!!!
What is it/does it do?
Presumably use a dll? - That's one thing I would like not to have to use... The only dll I want (have) to use is blowfish although I am considering simply using $hash(%var,32) as I think it is strong enough and I'm not using a HIGHLY secretive script!! 
As you have the command to add a listbox to a custom window, would it not be simple enough to have a similar thing to add one to a channel window?[/edit]
