A SUGGESTION:
Have text boxes expecting file names or paths automatically strip external quotes.
REASONING:
If I copy the contents of the properties of a windows Shortcut to a menu item,it might not work unless I manually strip external quotes. For instance, I am allowed to create a new application item with the following (including quotes): "C:\Program Files (x86)\Steam\Steam.exe"
But when I select that item from the menu, I am told that the target does not exist. IMO it would be valuable if QAP worked with or stripped external quotes that Windows requires in some circumstances--if I remove the external quotes, the item works correctly.
ALTERNATIVE:
As an alternative, the path should be validated when the item is created, rather than when the item is selected. A failed validation should give the option of editing the new item or even cancelling its creation...But even then, it feels like it should still work with (or strip) external quotes.
Currently the only behavior that suggests the item might not exist is that the icon defaults to one of QAPs icons, rather than the icon bundles with the app
