My plan is to completely move to Qt 5 by the be beginning of next year... this has some pros and cons as always. I hope by then at least *full* Qt 5 replacements for QtScript and QtWebKit will be available, otherwise I may continue to use Qt 4.8 primarily. But there's no way around Qt 5 in the long run... and QMC2 can already be used with Qt 5, only some features aren't ported yet (and will not be available because). The QtQuick 2.0 port of QMC2 Arcade's "ToxicWaste" theme also has some issues... I think that "darkone" mostly works though.

We're searching for QMC2 translators and support for existing translations. Interested? See here!
