Tweak sites the way you want them to be
sitemod is a Chrome Extension which provide an easy way of modifying sites to
match your preferences. Since the Extension API only allow loose permission
requirements; sitemod is Open Source to ensure as much transparency as
possible.
With a "no bullshit" approach, sitemod is easy to use without complex mappings
or large configurations. Give your mod a name, which URL it should trigger on
and what styles and/or scripts you want to apply. That's it.
