This helps with creation and getting values and should be safe since it still keeps lvgl on one thread at a time. Add OnLvglEvent to UIElement that allows foreasy place for UI Elements to respond to LVGL events . Add button class that can react to being presssed via a callback function. Add GetBottom() api to allow easy grabbing of bottom Y coordinate. use some new stuff in the settings page to sort test it all out.
