Sad to hear that it’s not fluent for you :(
We went for dual licensing (GPL / commercial) in hope of creating a sustainable project.
We do have basic focus handling but the demos don’t really try to show that off - that’s more tailored towards touch based input at the moment. But we’d love to have a17y, full desktop like tab focused etc.
Regarding the compilation: the ability to live preview individual components or the entire design and seeing changes being applied on the fly (we have an interpreter for that) speeds the ui dev cycle a lot. Give it a try :)
