Interesting! Tiddlywiki with all of it's plugins, tags, search amd markdown support is still preferable to me. It is even more crossplatform as it works locally in my Quest as well (termux webdav rb script)
I quite happily and successfully used MPTW to manage work knowledge, tasks, and context for 2 years. Between leaving the related job and the odious save workarounds for pre-TW5 wikis, I stopped using it. I've made multiple multi-hour attempts to find a workable TW5 configuration, with both the TW5 legacy plugin and searching for replacement plugins.
Not sure if you have run across NoteSelf (https://noteself.org/) before, but it is basically TiddlyWiki + PouchDb. Maybe that would be a workable solution for you?
