Extra features for SFGC (http://gc.gamestotal.com/)
Anfit's Mods begun as a Firefox extension, changed to a Greasemonkey userscript, finally to become a Chrome app.
It's a bundle of small tweaks to a MOSS game Space Federation Galactic Conquest (http://gc.gamestotal.com/), from UI niceties to new Ajax-driven user interface for commonly used functionalites. It also incorporates common knowledge (recipies for in-game items, etc).
All mods are listed on the repo main page (https://bitbucket.org/anfit/gc-mods) short explanations. Virtually all of the tweaks can be toggled off.
