I am using this kind of links in notes:
message://%3c1250799563.382729.1691143175130@email.taboum.com%3e
on macOS these just open the referenced message in Apple Mail, from any application. Including Joplin.
Unfortunately Joplin doesn't recognize these and make the hyperlinks automatically as it does for http ... etc
So I have to create the hyperlinks manually.
Good idea and possible to include these
message://*
as hyperlinks?
