On the Android app when planning a flight returning to the originating airfield you are given the set radius options of Fly within 5.0 nm, 10 nm, 25 nm, 50 nm.  Would it be possible to have a box (or figure up/down selector the same as the Windows desktop version) where a custom radius could be input, or edit the function of the current Find Landing Airfield search box which accepts airfield name or identifier, to accept a number for nm?

Thanks
