Greetings,
Does anyone know a way to determine what installed add-ons are actually being used on a site? I have a lot of sites with tons of installed add-ons, both free and paid ones. On some I went way overboard testing out add-ons, etc.

I would like to clean these sites up by uninstalling unused add-ons. I was hoping for an easy way to determine this other than going to every block on every page and taking notes. Perhaps a way to list every block type used in a site?

I have a vague memory of a way to do this, but I'm getting old so it may have been a dream...
