For now, the major pain points I see, are the bound values (px, rems …) and the context. Other than that, even though it required some tinkering, everything seems to be amazing 
I managed to do already some things, that would save like, tons of time actually. And I’ve not even started…
The groups (for the fields) might end up being a nice to have too, as actually, I’m planning to make it like suuper customizable.
The only thing I think is gonna be a weakness of these overall for now, is the lack of the ability to either have, or set up more triggers such as pointer events, and keystrokes.
Edit: An idea might be, to actually make the various fields have a group such as variables, or collections, and maybe making those groups become the groups like in this picture? I’m not sure if it would make sense.
