Alright, my Mastodon CSS tweaks are live on GitHub :) https://github.com/nileane/Mastodon-PeachyTweaks

Available in 2 color variants for now : Lemon 🍋 and Peach 🍑

Tweaks so far include :
- Set a custom accent color
- Hide several redundant UI elements
- Trim down the UI for logged-out visitors
- Tweaks to profile fields (no 'Joined' field, less obnoxious verified fields)
- Little fancy things here and there (ie. backdrop blur on headers)
- The bits of CSS that support my custom About page (https://nileane.fr/about)
