Responsive, touch-friendly UI - great for tablets and mobile
Super simple config in YAML - because if it's not YAML now-a-days, it's not "cloud native" :-)
Dark mode - for those of you that roll that way.
Accessible - passes all the accessibility checks in Firefox, and issues with accessibility are taken seriously.
Container - available for quickly testing and getting it up and running, great for the selfhosted community.
Integrate with anything - OliveTin just runs Linux shell commands, so theoretially you could integrate with a bunch of stuff just by using curl, ping, etc. However, writing your own shell scripts is a great way to extend OliveTin.
Lightweight on resources - uses only a few MB of RAM and barely any CPU. Written in Go, with a web interface written as a modern, responsive, Single Page App that uses the REST/gRPC API.
Good amount of unit tests and style checks - helps potential contributors be consistent, and helps with maintainability.
