I think I've got it how I want it now. At a page level I've....
- Got rid of the coloured background I can't get on with.
- Got rid of the oversized header at the top of the page.
- Stopped the small header being fixed so there's more room for content (I'm usually opening links in new tabs so don't need to navigate that much).
- Got rid of the Social Media bar - was just clutter to me and I paste plenty of links to LZ on Facebook.
- Kept the Navigation bar - might be useful, but I may get rid at some point.
- Kept the Google Ads - want to get rid, but it helps LZ
At a post level I've...
- Got rid of all highlighting/background colours.
- Kept the poster details to the left allowing messages to follow directly under each other and take less space (height/scrolling) on the screen.
- Shifted post links to the right for the same reasons.
- The details about the poster are useful, but generally only for new people I don't recognise, so I've made the pop up on the right when I hover over the posters name or avitar (see 3rd post in pic below).
This works really well for me. I always view full screen, so the message content spreads out to the page width unlike in this pic. I'll turn my attention to the forum post listings etc pages, but I'm really happy with this so far.

For info on how to install it, this is where I found the info (the Help menu is now on the '3 horizontal bar' button in the top left of the screen and the '?' button from there)

This works in FireFox, other browsers may have similar ways of overriding styling.
