Fpcurator doesn't actually seem to grab anything from a games [ItchioDeveloperName].itch.io/[game-name] URL other than the embedded game itself and the embed resolution that page specifies, so using a games html-classic.itch.zone link for its launch command and file structure would be more accurate. The former is still good for the Source field though.
(For example, https://seansleblanc.itch.io/pico-8-fillp-tool vs https://html-classic.itch.zone/html/953669-641520/index.html)
It would be nice to have a toggle button for whether or not to reference the [ItchioDeveloperName].itch.io/[game-name] URL for the embed resolution as well, since I've encountered a few games where using the default html-classic.itch.zone resolution makes them display more properly.
(Also in some cases, when the webpage has a lot of detail added to it by the dev, I prefer to just curate games with their actual [ItchioDeveloperName].itch.io/[game-name] webpage, so this'd help tell at a glance if that's actually the webpage I've downloaded when mass-curating. Maybe there could even be a toggle in fpcurator to use that webpage instead when autocurating? But that's a different request lol)
