In the site activity megathread some suggested users ought to have some way of knowing just how much of a thread they're occupying. I added a userscript just for that purpose to the MefiScripts repository. It puts summary stats just below the comment box. [more inside]

With help from pb, I've put together a Greasemonkey userscript to display the old "x new posts and comments since your last visit" message that's been removed from the new Modern Theme. [more inside]
A lot of people have complained about FanFare's professional white background. Well, DRUNK WITH POWER after somehow kludging together a successful CSS theme for /r/MetaFilter with zero experience, I decided to try my hand at giving our new subsite a makeover, too -- the layout is fine, but that glaring white is painful to read in a darkened teevee room. Inspired by the original soothing dark blue color scheme from film/TV review aggregator Metacritic (which discarded it for an unpopular redesign years ago), I put together a complete FanFare theme (screenshot*) that adjusts not just the background and text, but stuff like visited links, link hovering, the pop-up video button and lightbox, posting page notes, live preview area, and the sidebar and Deck ad box. You can install it in Firefox (with Greasemonkey or Stylish), Chrome (with Stylish or Blank Canvas Script Handler), and jailbroken iOS (with Userscript Loader, using this URL) -- it's tested and working properly on all three.
