You will need to install a user script manager extension to install this script.
Conversion from userstyles.org edition to UserCSS. A style that makes all tasks yellow, unless they're complete/not-due (grey) or rewards. Cobbled together quickly, so there might be an error somewhere, but I've tested it and haven't found any in the latest version! (That's a lie but this description is currently exactly as it was from USO--I need to slightly modify the shades, and the reward bug listed below no longer occurs... though that may be because of a new behavior where no tasks take on the yellow shade in the edit modal.)
Original USO creation date: 2017-07-23
Original USO changelog:
2018/01/19 - CSS classes changed drastically and forced a complete rewrite. Style was updated accordingly. I did it kind of fast, but I think it's working fine!
2017/10/13 - It was easier than I envisioned to update this theme, so... updated to work with the new site! And no issue with rewards backgrounds because of how the new site's CSS works!
2017/09/29 - This no longer works after the site update. If I remake it, I will probably start it from scratch, so this might be archived soon.
Code is really messy (because it was originally envisioned with more functionality, which it might get later). May need some hammering out and fixing later
Known issue: The background of the title of rewards in edit mode is yellow. I believe this is because rewards technically have a value? I tried all the ways that should have logically fixed it, but I couldn't get it to fix, so I'm posting it as-is.
