Thank you very much, and I also agree with your points: Electron Apps simply never feel right, even if I work within them all day (VS Code for example).

I also agree, wxWidgets is quite great, although I have to also agree with the comment above, that C++ for a GUI library is just a PITA when used from any other language. AFAIK the consumers from wxWidget (wxPython, wxErlang?, ...) are using a C wrapper around the C++ wrapper to use it.
