Hmm… they aren’t putting much on the clipboard. Basically just an URL like this:
obsidian://open?vault=Obsidian%20Help&file=Advanced%20topics%2FAccepted%20file%20formats
There’s an public.url-name type that they put on the clipboard, which is supposed to be used for a title, but it’s empty.
You may want to send feedback to Obsidian for this one. They’re putting the URL in the public.url, public.utf8-plain-text, and even NSStringPboardType type. But it would be nice if they can put an appropriate title, say “Obsidian Help File: Accepted file formats”, as the public.url-name entry instead of an empty string.
At the very least, if someone pastes an URL without a title, I can see if it’s a custom scheme (aka not http:// or https://, like obsidian://) and use that scheme name for the title: “Obsidian link”.
