Airgram improvements

[FlyingRockDoctor]

For private pilots, Windy provides a valuable tool for flight planning.

A few suggestions that Windy might consider to improve the Airgram profile:

• provide altitude in '000 feet

• option to top out vertical scale at 10,000ft (for private pilots)

• option for local time rather than UTC

• option to enlarge the Airgram to be make it more readable and downloadable

Thank you for creating such a superb application!
