This is a really interesting workflow. I like that states now exist inside the overrides panel, and I think that the ability to compound those colours or shades is valuable. But I’m finding that the setup takes a long time. The cognitive load seems quite high, especially because I could create a shared style much more quickly.
On that note, I would absolutely love to be able to somehow (natively) integrate shared styles into overrides to be able to be able to choose the state of button.
This also might be incompatible with some workflows, especially when using plugins like dynamic button.
