I am building a custom org mode like plugin and would like to support something like column mode.
This effectively shows a text layer over every visible heading reflecting certain properties of the item. The overlay behaves like a row in an org mode table. This gives the user a really powerful way to edit properties across a folded document. It also gives the user full context as only the heading is visibly different and headings can be expanded for a quick peek while planning.
I am trying to think of a non destructive way of accomplishing this in sublime. Phantoms struck me as a potential item but they cannot receive input. Is there any other tool for altering the buffer visually without destroying the actual contents? I will go down the temporary copy road if that is the only alternative but in a large org mode file that could get very expensive.
