Not so much Opt Editor, but in the S-Foils Editor it would be handy, because in perspective it's hard to judge the level of the landing gear, with a flat view you would be able to see if the landing gear feet are at the same level or not.
a button the same as the other buttons would do, just an on/off button just to switch it from perspective to flat view
Also, is it possible or not to add a slider to the S-foils, so left would be closed and right would be open, when you slide it you'll see the rotation of the s-foils or gear, don't worry if you can't do this, the perspective button would be more important to me

Please let me know if it's possible or not for either suggestion
Thanks so much
