Battery level and Volume control in config file

Your second question first.

You have 2 blades, the main blade and the switch.

If you just look at what’s different between the ones they had compared to what you added, you’d see that the second blade style StylePtr<WHITE>(), and the “name” at the end of the preset are missing from the presets you added.
That is why 1. the switch doesn’t do anything, because you have no style for it and 2. you don’t get an error about the number of blades not matching number of styles because you didn’t include the “name” at the end.

As far as Volume Menu sounds, if the font doesn’t contain vmbegin, volup, voldown, vomend wav files, then you get beeps instead.
Either just copy them from another font that has those, or you should just have a ‘common’ font folder setup, where a copy of sounds in there would act as backup and get used for any file the first font in the font search path doesn’t have.
