Add a "family" option, where you can create "families" on the page with all your planes, and add them into one with the edit button on the plane. This would be really convenient IMO, since you'd obviously be able to view the "families" on a new page.
@Thefalloutplayr That would also be cool, but probably harder to implement.
And a joint plane builders thing you can choose a tag that's joint task force and you then choose the people allowed to download your plane. Cool not!?
Make simple planes great again!
