i think it's probably better to do this via a msg
so basically there would be commands like: gui-hide-menu gui-hide-scrollbar gui-hide- ... gui-canvas-fullscreen gui-hide-decortion
I would second that. just embedded in normal pd programming.
Provided this fullscreen feature, (how) do want to be able to scroll the canvas? I suppose we just keep the scrollbars...?
it's possible to scroll without scrollbars - you just have to know
yourself that there's something there. I would say that optional
scrollbars (such as optionall everything) lends to more possibilities.
