The current Style Manager, and the way Webflow handles global and combo classes, can be a bit confusing and unintuitive.
I'd like to propose a new way for handling classes, which mirrors Block-Element-Modifier (BEM) conventions.
Here's how it works:
Each custom class is now entirely an abstraction. Classes only convey that they are a div or something else that's very basic.
Using / or __ in the name has the effect of creating a folder.
If you have two classes named "Block/{class}", or "Block__{class}" and "Block/{class}", then they'd both be under the same heading of 'Block'. (This is a bit like what happens in Sketch, or the Bear Notes App)
The modifiers to those classes determine the look and feel of their assigned parent classes.
All modifiers are global and interchangable.
More recent/specific modifiers override prior modifiers.
As for precedent: someone could already employ this strategy if they wanted to. I've used c-abc to denote abstract classes to divs, and then applied global classes/combo classes on top of them to govern how they look and function.
What I'm proposing would make combo/global classes more intuitive.
