So I just stumbled upon this wizardry: An edit link that appears when I hover over a question's tags, which allows me to quickly edit them without leaving the page.
At first, I thought I'd been blind and missed it these past couple months, or maybe it's a new feature. However, it seems that it's been around for a while and is part of the moderator tools privilege package, granted at 10k.
I gotta ask: Is there any reason for this? Seems like it'd be a convenient thing for everyone to have. After all, you unlock inline post editing along with edit privileges — why not lower the bar significantly and make this part of the retag privilege?
