+1 for the ability to create both card decks with only (predefined) plain text content and ones with a blank text entry field would be extremely useful, the former could serve as condition/status markers, treasure cards and other notes/items quite nicely whilst the latter is honestly really necessary for games like FATE which have an aspect based economy, and where such elements frequently need to be generated on the fly (and not always by the GM). I've recently been trying to port the card-game Icarus into Roll20, and although most of the elements are pretty easy to convert over (even with my extreme lack of knowledge about how Roll20 works), the essential part of the game involves collaboratively generating Aspects that are evolved as the rounds of the game progress, and thus need to be accessible, and viewable, by everyone in the game. In PnP this is accomplished through a shared set of notecards, in the current cludged together version I have produced I am relying upon the old favourite of using a rectangular shape overlaid with and locked to a text box, however this is very clunky and has, during the couple of tests I have run with friends, led to delays and confusion with people unable to work out how to enter text, accidentally separating the text box from the rectangle or just generally delays when/if we run out of pregenerated 'cards' and I need to quickly try and recreate one for the next Aspect.
