add support for pictures (arbitrary positioned incl. as background) - at least to the presenter
very basic interaction among the tools (e.g. find a way to put result from draw to presentation)
for each app add support for custom styling (maybe a separate input form for JS which could then be arbitrarily used to write styles for arbitrary elements - assuming elements, e.g. spreadsheet cells, can be easily referred to)
I'd envision this "advanced" functionality:
Thoughts?
