As you may or may not recall,

one of the features added by my
Tinker Tinkering addon is to modify the tooltip of tinkers that grant talents to include a description of the talent they grant. It occurs to me that that sort of modification could be useful more generally, since there are lots of objects that confer talents when worn or carried. Thus my new
Talents in Tooltips addon.
This addon adds the game option "UI | Conferred talent description in tooltips", which does basically what I describe above. The default setting is Never, which keeps current game behavior; the other options are Single, which only adds a talent description if the object confers only one talent, and Always, which will add descriptions for all granted talents, even if there are several (which I can imagine could potentially get unwieldy, hence the Single option just in case).
[Looking ahead, I could maybe see this going into a future release of ZOmnibus, depending on how people feel about it.]
