I upgraded Orion this morning, and now see the "Copy Cleaned Page URL" option -- thank you!
That said, in the very first example I tried, it was greyed out. I suspect that's because none of the parameters are known trackers, so it's not critical to be able to clean it. But it's still pretty full of junk: https://yourlocalepidemiologist.substack.com/p/what-im-learning-from-maha?publication_id=281219&post_id=165129290&isFreemail=false&r=nnnnnn&triedRedirect=true
Basically everything after the ? is junk -- not damaging per se, but empirically all unnecessary, and I prefer not to include it when I'm sharing links to this site. (Which I do frequently.) I'm especially concerned about that opaque r parameter (which is why I've replaced the value with nnnnnn here) -- I don't know what that is, but I could easily believe it's a personal identifier of some sort.
So it would be nice (and I acknowledge that it's not earth-shakingly important) to be able to configure what "cleaning" means, probably on a per-domain basis.
Hard to say exactly what this might look like, but my first-cut guess at a UX to try would be a per-domain Setting, which could be called up by a hotkey for the current page, listing the parameters that are shown on the page and allowing one to disable them on a granular basis, as well as a simple "Clean all parameters" option (which I would probably use for this site).
