One feature I think is useful in NotSSG is its server friendly, automatic cache busting. NotSSG cache busts every 15 minutes of the hour, meaning your visitors won't have to do a full reload (Ctrl+F5) and Neocities servers are respected. If you prefer however, you can also trigger NotSSG's cache busting instantly/manually for your visitors by declaring "CACHE_BUST: [some_number]" in the config file.
