I've been working on a lightweight Chrome Extension and it's been really, really frustrating. The documentation is all over the place and it's sometimes unclear what's for v2 vs v3, and there aren't any deep-dive guides for solving non-trivial problems. There also isn't really any tooling for development besides "reload the extension in Chrome and see if it works."
