Apart from deeper technical issues: I don't like how wxWidgets look and that touch is seemingly not considered a first-class citizen like mouse+keyboard (yet).
But wxwidgets is just the actual native user interface?
It largely looks like WinForms. I prefer the looks (and touchscreen-friendliness) of WinUI by a huge margin.
Replying to myself as I cannot edit now: and therefore since wxWidgets is the native user interface, it has no "look"
