Topic: [Feature] Tooltips for "pool #", "set #" and "forum #" links

Requested feature overview description.
The tooltip for thumbnails provides info about a post (tags, rating, score, uploader and date). I suggest that we have the same thing for pool, set and forum links, where the title is presented in the tooltip (among other info, like creator and date?).

Why would it be useful?
It would provide info about what pool, set or thread that has been linked by other users without the need to click the link.

What part(s) of the site page(s) are affected?
Where pool #, set # and forum # links can be posted, such as threads, blips and comments.
