Thanks for the suggestion.
With the new member portal, after uploading photos into workshop, if you do consective move opeartions to aircraft/airport section, airport code should be kept and populated automatically. But make it permanent sounds like a better idea.
Here we need to make a choice between "last used airport with move action" and "airport code on member's profile". I'd like to hear our members' input.
As for shot date, the workshop can read EXIF data from photo and auto-populate the field, unless for some reason the EXIF data is stripped when using image processing software. Maybe we can use "last filled date" as a backup to the above.
