Barry,
I've been checking out your EasyOS project (really enjoying it overall) for the past few days and couldn't help but notice that Appi doesn't really provide many packages. Considering the software constraints already inherent to the OS, I thought you might be interested in looking into AM/Appman https://github.com/ivan-hc/AM (different iterations of the same system) which is an AppImage package manager that would seemingly be incredibly beneficial to integrate into Appi. It has 2500+ programs https://portable-linux-apps.github.io/ ready to go out of the box.. It has some great built in features you could utilize if you chose to including simple turn key sand-boxing and easy updates.
