Yes I'm thinking about fluent design widgets/theme.
WinUI sort of has fluent, but it is extremely inconsistent. When should things be rounded vs squared? It’s completely inconsistent internally.
Even if Qt wanted to go fluent they’d have a hard time finding any concrete examples to work off of. I can’t think of any “fluent” apps that are consistent with themselves, consistent with the design system, and not breaking major rules.
Sounds like an opportunity.
