gZany well it's a good start although this is also how fullscreen is achieved with applab.... this makes it harder because if you don't label everything you want to keep track of in the program you'll be forced to inject it again with innerHTML, while it's "not that big of a deal" there are a bunch of sanitation that happens which pisses you off like for most it makes sense though it's dumb for other reasons, there is a fullscreen application that I'm currently working on which i may release soon, also this type of fullscreen has weird scaling issues which makes it harder for dynamic scaling rather than just hard coding it, otherwise it'll come out weird
tldr; (anything within the tag of divApplab is editable)
if you decide to make a full app this way you better be prepared for more responsibility with things going wrong
