SearchSuite is a userscript that provides user control over search results: it can strip them down to a single-spaced list, sort, and more. Most of its features are presented as menu item toggles to turn each feature on/off. Each menu-item-controlled feature works on the output of all the others, in both their on and off states. Feedback and feature suggestions welcome.
