1. You can set up color filters for namespaces, types of edits, log entries, and more (or even filter out namespaces). Recent Changes didn't have that before, it would just be a wall of bullet points. However, the spacing between lines has decreased and I think that has harmed readability as well.

WikiActivity was a custom feature, Recent Changes has always existed. There is a dev script for it, WikiActivity. It's very barebones.

2. NewFiles is the standard MediaWiki page, Images was a custom feature. I miss the use cases and the captions, those also miss on images in category pages. I believe that's been ticketed as needing a fix.

3. Unfortunately, CategoryExhibition was bad SEO. Categorization in general is as every numbered page is counted as a duplicate of the first. With only 16 per page, that's a LOT of duplicate pages which tanks your SEO. Dynamic Categories was set up to counter the SEO issues. This is one of those cases where UX and SEO are at odds.
