The problem with switching the theme is actually a problem of all those stored colors in all widgets and data. E.g. what to do with AttrText that has some dark adjusted ink stored in it.

U++ can actually switch the theme with immediate response (just check upptst::ChStyle, it does just that - but notice that background in example ArrayCtrl does not change), the reson for restart is actually to make developer's live easier.

But OK, I can add "SkinChanged" virtual method and leave the immense work of reskining color in developer maybe...
