No idea if this is even possible, but what do you all think of a plugin that simply hides the entire UI *except* the chat window? A toggle button to perform this action would be perfect. Your thoughts?
I don't think it's possible yet. Your best bet would be some sort of minimal skin I think.
you could try to make secondary ui layout too.
first take a copy of you regular ui which you quest etc with
/ui layout save quest
and then hide all the possible things you can like quickslot, minimap etc from the options etc etc and do a rp layout
/ui layout save rp
to switch between the layouts you would only have to type /ui layout load quest or /ui layout load rp. When you have the layouts you can also make them an alias or quickslot button to make the switch even faster.
/alias ;rp /ui layout load rp
just type ;rp after this in chat window to execute the whole ui command
/shortcut 120 ;rp
to make a shortcut (not entirely sure if that is correct, can't remember as i don't have client open)
the layouts even save the skin info so it could switch to minimal skin when you load the rp layout - and vice versa
