Line Style: Buttons hidden in Fullscreen mode.
Locus Map: V3.27.0
Sorry Menion, I know you have no love for how Android handles Immersive (Fullscreen) mode but here's another one for you. :(
In the V3.27.0 Line Style panel, the buttons (Cancel, Save) are hidden by Android's system menu if you use any one of the three drop-down menus (Pattern, Coloring Mode, Width). In this example, I opened the Width menu, the system menu appears and remains visible after the Width menu is closed. The Cancel and Save buttons remain hidden and can't be used.
