We really need to be able to apply/modify image type parameters within a project environment rather than having to open up a family and adding them there. No other parameter behaves this way. Its clunky and un-intuitive for most users.
Yes, I know the idea exists already. One is linked below. But as I've said before, adding a like to that does nothing to make it visible again since its five and a half years old. Would be nice if adding a like popped it up to the top of a recent activity list... Feel free to combine.
