It was before in the Unity 3 days, very handy indeed. I hate clicking all the members one by one to see their type or the parameters a function is supposed to accept especially that there isn’t much info besides that.
Also the number of classes in Unity has never been higher so it helps to run through them in one single look, I think I also remember there was more details of the members in class page and their inheritance info as well.
Can I count on you doing something please?
Sorry I needed to bump this up 
Thanks for flagging this up, I agree they should be there. I’ll see what I can do.
