[Issue]
Sometimes, I'll go into the search bar and search up a certain term, only to find much later that it had either been invalidated or aliased to a different tag. It's rather annoying, and I haven't been able to find/create an external tool that I could just jerry-rig into the page via Greasemonkey.
[Proposal]
I would like to propose a tool that will open a small message under the site news banner that tells users/visitors that the term(s) they looked for are no longer in use, and if the term was aliased, what it was aliased to.
