# This little script has been written only to show we could select which
# apps or actions we would present in the 'open in' menu.
# It allows user to select among an non exhaustive list but with
# some ones I have identified during my tests on a .gpx file.
# Of course, the list depends on the file type and on installed apps.
# Non Apple Applications of the first row (share), all return 
# 'com.apple.UIKit.activity.RemoteOpenInApplication-ByCopy' as service name, 
# thus it is not possible to identify each one while you don't know their uuid
# Each app of the 2nd row (Action) can be identified by its service.
# If you selct 'all', the script will show the standard menu.
# AirDrop has also a particular process because to exclude it, you have to 
# set it explicitely in the ExcludedActivityTypes. 
# It seems impossible to hide the 'more' icons ('autre' in French), even 
# if they are empty.
# And I don't know how to directly open a particular app without selecting it
# if this app is the only one included, like the Apple Shortcuts app does.
