Why isn't there a save system yet? It could be understandable for a demo version maybe the early 0.1, before any actual tangible progress in terms of content is made, but at 0.17b, when almost every page contains the "Needs a save system" type of a comment, it's quite surprising that it hasn't been implemented yet. And it doesn't seem to have any changes done, even though a version change happened. A change log would be very much appreciated, even if it's just the optimization of existing content.
