History of wiki client and server technology, Sinatra/Ruby to NodeJS server; jQuery based front end web client; evolution of features and mechanisms under need; keeping features and mechanisms spare and not overspecific, allowing discovery of new solutions a few steps away from the current implementation.
History of plugin development, originally Typescript running in the server context, with access to environment globals to see what pages are present; running a build for a plugin became increasingly tedious, so there has been little new development, especially since Eric Dobbs' work on the Frame script and post-message coordination of content from a frame to the page content.
