The GM in one of the campaigns I play likes to move to a different roll20 campaign with each major adventure. There may be technical reasons to do so or not to do so (such as roll20 may or may not have performance issues with so many tokens/maps all in one if we were to merge them) but regardless of technical reasons, it is his preference to do this. Now on my end as a player, I wish I could go back to the previous adventure, pull up my macros, and just get ALL the macros at once into clipboard or file. Then go to the new adventure, and recreate all those macros again by just pasting into a window or importing the file. That would make moving from adventure to adventure soooo much easier and faster. There is an additional benefit as it makes editing all your macros each time you level up or gain an item or what-have-you, if you could edit them all at once like that (like in a file or all in one text-editor..) ... you could see all your bonuses at one go.
