Import-Export of Flight Plans in .pln and .fpl

[TTC70]

Is your feature request related to a problem? Please describe.
It is not exactly a problem, but a feature which could ease the work of many pilots.
At the moment the only two versions of Flight Plans managed by Enroute Flight Navigation, are .GeoJSON and GPX.

Describe the solution you'd like
It could be very helpful to increase the compatibility of the app adding the feature to export or import a *.pln and *.fpl flight plans.
The following open source application already takes into the account the conversion between GPX and FPL format.

Could it be an inspiration for the programmers?

Describe alternatives you've considered
The only alternative is to use an "out of the app" application and convert the flight plan "off-site" (or "off-app").
