Think I might drop a suggestion post for this and one other feature I think sheet workers need if my fellow sheet authors want to support the idea. The other feature is that there needs to be a way, short of API, to cause a campaign wide update of characters since changes to the sheet workers can have drastic repercussions on how a roll works. Edit: also, yes, this is exactly what I meant: G G said: Do you mean something like this: The HTML creates an attribute named OldName You rewrite the html, and the new stat is called Old_Name Now the character sheet is full of legacy stats called OldName that aren't used any more and dont exist in the html In a situation like this, it seems like you should be able to delete the old attributes, but I don't see how. It seems like an oversight.
