If you have a Samsung, Goodlock can edit the share sheet down to the very app, as well as favorite contacts. I’ve also been using LinkSheet (available on F-Droid) with ClearURL to open links notorious for nasty redirects, and it may help with some of these features you’re looking for.
I also noticed a gap, and I’m wondering if it’s where the ad banner is now. I really hope not and that this is just a visual bug, because it’s pretty glaring and distracting.
