Yes I mentioned they have finally added them. I've been using Blender a lot longer than 3 years and it is quite an embarrassment that it took them so long to add them.
Looks like proper tooltips were added in 2014. Blender was first released in 1998! 1998! 16 years to add tooltips!
They aren't, and Blender has them. I think it's had them since I started using it, about three years ago I guess. Although they've definitely improved in that time.
