Open, Save, Import, Export Flightrack sometimes confusing

[Reimar Bauer]

open and save handles ftml files. This is the mss based format

import, export can handle plugin driven formats. The extension can be set in the mss_settings.json too.

May be we can have a validation check if a user tries open. On a not compatible file it should message that the used file is not standard file format and he should look on an import extension.

So instead of the raised Exception by the XML library, you'd like to have a hint at a wrong fileformat? I mean, if the thing can be parsed it is a valid file, if it can't it isn't?

[Reimar Bauer]

over engineered, right exceptions should do that
