Hello,
There used to be an addon I had, I believe it was tool-tip and some other one, that allowed for me to mouseover a mount on a nameplate (like the buff bar) and it would show me the location drop of that mount.
Ever since the new UI changes, this no longer works. Currently, I can mouseover a mount then take that name and type it into the search bar, whereas before, it would just tell me where it dropped.
I miss this feature. Especially for collectors. It also worked for other collectibles.
