Latest nightly no longer has "Auto Detect Site Info" in Add Link. I use it in 1.0rc4 a whole bunch.
I found and old plugin that still works with a small edit so it activates in mu-plugins instead of plugins. But now . . .
The reason I looked at latest nightly is because I wanted to add the "Auto Detect Site Info" button to the Edit Link page, too. You know, to update descriptions/titles of feeds/links in my/users blogroll automatically.
Now I want to know if it would be possible to tweak the plugin so it works on both Add Link and Edit Link pages.
