**Heads up: all three are still in beta!** I'm not a full-time developer, just an AV guy who knows his way around code, with some help from AI. I work on these in my spare time, mostly evenings and weekends, so updates come whenever I've got some time to spare. There might be a rough edge or two along the way.
