brent, the plugins are just a bit extra, and just as you say its main thing is to manage file-system images.
VentoyPluson
is the GUI for plugin management. Along the bottom left of this page, you can see the various plugins.
Some fairly obscure ones, probably the most useful to most, would be the Ventoy Persistence Plugin
This allows saving any changes you make to the live system, so that they are still present the next time you boot to it.
Good luck to the creator of, Ventoy! 😃
