- A very good program.
- However, F11 (Firefox Browser: Full Screen Mode)
Page Up / Down scroll operation (X)
- I hope this issue quickly improved.

Thank you bluenote!
Good catch, I never tested it in F11 mode! And bug very annoying, too.
I've already solved the bug and uploaded a new version 1.6.6.

Also, I put a "x" button in the topright of the menu, to hidden/show the menu, as Denzer asked for YT themes.
