That is exactly the reason why we support setting skin on startup.

See, I guess there is a certain mismatch of expectations. For me and for U++ users I care about, skinning is not that important. I just want the app look as much integrated into host as possible, do not care much above that. And most users do not switch themes 3 times per hour.

#ifdef flagMAIN
GUI_APP_MAIN
#else
void AppMain___()
#endif
{
//	Ctrl::ShowRepaint(50);

	Logi() << UPP_FUNCTION_NAME << "(): " << SplashCtrl::GenerateVersionInfo(' ');

	Ctrl::SetUHDEnabled();
	Ctrl::SetDarkThemeEnabled();
	...snip...
	LoadSkinSetting();

	// HERE IS A CLEAR POINT WHERE I CAN CHANGE THE SKIN ONCE

	// first line in ide/main.cpp where the GUI is used

Fixable, just forgot to fix it.
