0.9.7

Dealt with QML, added some keys and a theme, etc.

Please note:

If you've customized one of the extra themes, please restore its default settings after this update by clicking on the Restore button in Kvantum Manager → Configure Active Theme (or delete its user installations in Kvantum Manager → Change/Delete Theme) because backward icompatible changes may have been made to it. Then you could customize it as before.
