Hey man, just wanted to let you know that a43 for the Pi won't let you save menu settings (/ then S in a menu). I had to open it outside of Mystic's editor and make the changes I needed myself.
Workaround for now, change what you need to in the /S settings menu then
change a setting on one of your existing menu items then when you ESC out it will confirm you want to save while keeping the settings menu changes as well.
