Seconding TiddlyWiki. I use it as a personal wiki at work. It even supports LaTeX (via KaTeX)! Here are the customizations I found useful: * Table of Contents: By default, there is not Table of Contents in the wiki. So a TableOfContents tiddler was added. The tag $:/tags/SideBar adds it to the nav bar, and the field list-before controls the position. New entries are added to the table of contents by adding the TableOfContents tag. Note: the same code can be used in tiddlers to list tiddlers with a given tag. * Journal: New Journal date format was changed to YYYY/0MM/0DD (DDD, MMM DDth). This makes lexicographic ordering of Journal tiddlers to be chronological. That is, Journal tiddlers will be sorted by date when sorted by name. Visual theme: The layout was changed to fluid-fixed Settings - Appearance - Theme Tweaks - Options - Sidebar Layout: Fluid story, fixed sidebar Sidebar width: 350px This looks particularly well when occupying one half of a wide screen. Appearance - Code Foreground was changed to #0a5701 (green, used to be red). This affects the color of text enclosed by single tick marks. New Journal, Attachment, Configutation, Manager buttons were added * Plugins: The following plug-ins were added: KaTeX for LaTeX support; Highlight.js for code syntax highlighting
