VTOL for flaps is very common input among almost all planes in the website. What if there's an actual flap input and flap buttons in-game with arrows up and down. Increments are 25%. If we want to fully extend flaps, we should able to click the buttons 4 times, if we want half, then twice or quarter flap, then once. This feature should be added to wings as well as on the XML codes so we can both make flaps on wings and on custom flaps using rotators rather than pulling down VTOL slider.
