I have my students using multiplayer to do partner and group work on making HTML and CSS pages. They are making deep-ish (5 page branch length) choose your own adventure stories. Each time they make a change they have to navigate the entire tree of links to get to the child page that they have just edited. Is there any way to easily see a preview of child pages instead of navigating from index.html every time?
Not currently. The only way to do this (which is what I do), is open up the repl output, repl.co link, in another tab. Then, each time you run, refresh the other tab 1 or 2 times to sync changes. This should fix your problem for now. This feature is planned, they just don't known when they'll get it released.
