Just found a really great use of sidewiki. I have installed so many plugins on another website and had a hard time keeping track I have temporarily disabled them. I can now select the plugin tet and immediately add an annotation about it. It’s relatively secure since it takes admin privileges to see the page. I frankly don’t know what my alternative would be…
I also have sites where I want to annotate which plug ins worked on my other sites. I can now do this without going back and forth and only when I am ready to do just that.
