• settings for piston that would allow the piston to be unpowered, but have an adjustable resistance lvl for it from 0-100% resistance
• the beacon lights with customizable blink patters or delay (like a double blink) and a delay slider from 0-10 seconds
• cockpit parts, nowadays more and more people are making detailed interiors, I think that adding parts like artificial horizon (resizeable), altimeter (resizeable), fuel guage and speed guage (resizeable) and activation Group buttons, switches and levers.
• roll,pitch and yaw agle limiters (measured by degrees and while you mess with the settings the wing will have a visual for showing the range limit for that part -glass feuselage, obviously -better wing leveling mode for autopilot, every time i use autopilot it doesn’t keep the plane level, its either pitching up, down or rolling sulide to side sparatically -prop idle setting, more propeller styles -activation Group extend/retract for piston -activation Group rotation for rotators and hinge -activation Group brakes for resizeable wheels -and the overload mod for vanilla game on ios, pc, mac and android

I guess that all i can think of that can expand the possibilities of future builds and in turn reduce part count on aircraft because of dml edited custom, multi-part details that take up alot of parts on aircraft, for reference the usual artificial horizon that some have custom made can be anywhere from 5-50 parts, having one as a single entity would make that a single part
