About settings, it is not stored in QML. The QML code only provides default settings, that might be changed using either an UI, or modifying settings file in ~/.config/. If you really want to change settings, check ~/.config/SfietKonstantin/Widgets.conf, and mess with the variables You might reboot sysuid to make the changes effective. RC1 is release candidate 1. I will release it tomorrow and release the 1.0.0 in the 3th of September. For all features like new docks, please post them on the bug tracker. Thanks.
