In particular, it's very weird that "doesn't use native widgets" is presented as an advantage, given that apparently the result is that your apps end up looking like this on every platform: https://notes.sciter.com/

You can use native platform widgets with Sciter. If you will find one suitable.

It is just that there are absolutely no standard platform widgets (at least on Windows) for this UI. https://notes.sciter.com/wp-content/uploads/2017/09/notes-sc...

And even if there are some, integrating them with what your app is needed will lead to some mess like here:

Custom components a la Windows 2000, some in Windows XP with default styled Windows 8 stuff - the zoo.
