One of two features/additions would be nice.
Either the ability to select parts of our creations to be output, or to have condensed or broken down portions of character sheets.
For example, If I have a 5e character that levels up but nothing else changes, there is no need to print out spell sheets, all I would need is an updated "cover" sheet or the initial first sheet.
This would not be dissimilar to printing out only the spellsheets/spellbooks… but would be exactly the opposite
Um... Windows I guess... though I would assume that the output/export function is probably similar/the same between most OSes as it looks like they are template driven...
