One screen size with and without help overlay

[micheldebree]

Is your feature request related to a problem? Please describe.
The help overlay does not fit in screen for all users. There are two sizes; one with overlay and one without. You can scale the window in the config, but it is not possible to have a screen-filling sf2 and also make use of the overlay.

Describe the solution you'd like
One window size, with the help overlay somehow inside the window (maybe transparent overlay and/or multiple help screens)

Describe alternatives you've considered
I manually move the screen around to see all the parts of the overlay. Some parts I cannot see at all unless I scale down the window in the config.
