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.

Wikipedia:Typo Team/moss just got a fresh batch (from the July 20, 2018, database dump) of articles with misspelled words, and words missing from Wiktionary. Stop by and experience the satisfaction of fixing all the misspellings in an article on the topic of your choice!
Any article with more than three headings automatically gets a table of contents (TOC). The TOC is placed above the first section heading. All text above the first section heading is commonly referred to as the lead section. Depending on the overall length of the article, this introduction should not exceed one to four paragraphs in length and should summarize the article's key points.
If you do not like the TOC placement in an article, you can move it by inserting __TOC__ where you would like it placed. If you do not want a TOC on a particular page, add the text __NOTOC__ anywhere on the page; if you, personally, do not like the TOC feature, you can disable it in your user preferences.
