[Suggestion] Save Settings WITHOUT closing window about zeffui

[Zeffuro]

Currently impossible without rewriting the entire config section to be not in a popup but in the overlay itself.

Maybe move the config into ACT itself? It's how hojoring/SPESPE does their configs. Probably be a bit of work, but just throwing it out there. Admittedly may be more work; I'm not familiar with the backend.

Thanks!
