I'm missing the support for the "file"-scheme in the URL field.
I can enter an URL like "file:///home/andre/myFile" but the link only works with Web-URLs.
If you could also add the feature to send the password, username, etc. as an optional param on the call, this could be very powerfull to start local apps with the data from enpass.
Keepass have such a feature (https://keepass.info/help/base/autourl.html)
