All my plugins are dogfooded, but there’s a few that I deem necessary for any stash install, even if just for temporary development
log-console so I don’t need to keep on going back to the logs page and can just hit F12 for a quick overview
rebrand because I have too many stash installs
QxSceneCard, I’ve gotten too used to the look of it 
useragent for quickly debugging/ updating scrapers
