Don't forget the custom Apps / Drivers are just that, custom and mostly "use-at-your-own-risk". While Hubitat staff may enforce some level of control in extreme cases, Community developed content is largely left to the Community to manage and curate. That said, Hubitat Staff are by no means against Community developed Apps and Drivers, as @bobbyD demonstrated with his link to a Wiki page setup to showcase our wares.
Another place to also search through would be the Apps and Drivers listed on the Hubitat Package Manger (HPM), a go-to for many, if not all, developers to make their creations easily accessible to all.
