This comment introduced me to TiddlyWiki, and I am quite happy with it so far. Does anyone have a recommendation for a markdown plug-in? The markdown plug-in from their website is no longer available. Thanks!
Here [0] is a link to a view I created that links to a markdown plugin (which should still work) as well as to information about TW's plugin architecture. If you're interested in learning even more about TW's internal architecture, check out their developer documentation here [1].
