Cider (and p4/g4c etc) was amazing when I left back in 2020, I loved it so much, and truly miss it. I rejoined Google last year, and they'd replaced it with a VSCode clone that truly was just a glorified text editor and most were all-in on mercurial as a piper/citc shim -- I was only there for 5 months before I decided not to stay, and I never managed to get Go type definition hints working.
