Personally, I want the duality of seeing every post and every vote where I’m a mod, but I want to drop all negative votes entirely everywhere else,
Have you tried using an alt to mod? That way you can have different settings on each account. Well, you would also need an account on another instance than LW, settings to display only upvotes appeared in 0.19.4 IIRC
You can try, but you'll probably get flagged
