Naw. It would be like going backwards.
Constructs event sheet is the defining advantage it has over clickteam products.
Ashley, construct’s main developer, made plugins for for old clicktem products before making construct. So he’s well aware of that old grid checkbox stuff, and he made something better. So much better that clicktem finally is making its event editor look more like construct’s.
To me that checkbox stuff is a lot less readable, and yes I have used it before.
