+xDefinately a very good idea.
Also a bit disappointing was, when I only modified one digit (i.e. 8000 -> 8500) the number was not accepted.
I always had to retype the complete number.
it‘s realized in the current version as mentioned above
in case of preselection VFR you get 1500, 2500, 3500 etc.
in case of preselection IFR: 1000, 2000, 3000 …
in case of preselection MIXED: 1000, 1500, 2000, 2500 …
quite comfortable now
