Hello. My suggestion… if possible. Especially useful, for users designing an aerospace vehicle.
Possibility to add / configure commands on the menu:
1) Landing gear = G
4) Cargo doors = C
2) Air breaks = B
3) Flaps = F
4) Door = D
…
Components mechanics example:
1) Select the components that make the landing gear (wheels & cylinders)
2) Make a group with this items (they'll work as an entity)
3) Assign a key to the group (selected components)
4) The group will go up/down | open/close
Best regards to all
