Here are 2 newest Tampermonkey scripts, I’ve made.
First was suggested by @randompersonjci and it allows to hide (through the Settings panel) selected buttons from the top menu (like Forum, Blog, FAQ, etc.).
The second one was suggested by @Nseraf and it makes the overview panel (the one with the Start Playing button) movable. You can drag the panel wherever you want and it’ll stay there, even after refreshing.
