@woltiv let's say you have a few #tiddlywiki html files in a directory, and you want to serve them up to edit in your browser on localhost port 8080:
rclone serve webdav --addr :8080 ~/dir
then hit 127.0.0.1:8080 in your browser, and you'll be able to edit, and autosave will keep the tiddlywiki html file updated on disk 馃槑
