Howdy Sancti and welcome to the forums!

keyclone's maximizer allows you to layout your regions how you wish. if that means you want to leave an area for your chat app, that's up to you. you could use a 5 region layout and only run 4 regions... leaving the 5th free for a chat window (i've done this in the past)

if you have any questions, please feel free to drop me a note.

have a great night and welcome to the addiction,

Rob (keyclone developer)
