Quick bangs alone almost make it worth it for me. The functionality exists in other browsers but it’s not synced, so being universal in the search engine itself is a giant usability improvement for me. Especially when using in conjunction with Orion.
I’ve used it on a couple of headless machines over the years primarily as a host for docker containers. It’s been mostly great but those few times it has broken was really annoying. Nothing I couldn’t fix and never needed to reinstall though.
That being said I’ll be reconfiguring soon and I thinking about switching away and using Debian.
