Are there any functions that are not used in REW ?

Rew is a software full of very useful features and becomes more and more complete.
We are all always asking for some new features to be implemented so I wondered if they are all really necessary and of great use.
For example, I don't use the scope function, perhaps because I have several dedicated instruments.

And do you use all the functions ?

The intention of my post was not to criticize REW as I think it is one of the best electroacoustic software for hobbyists, if anything to give feedback
on the real use of all the multiple functions.
I use all the principal measurement functions Response, Impedance, RTA, and waterfall, a little less than the others. What I don't use at all is just
the Scope function because I have three oscilloscopes in my laboratory.
I'm not ruling out that someone can use the Scope function because they don't have an electronics laboratory.
I agree with Mr. Wayne who says that hardly a single person uses all the features, but REW satisfies all of us electro-acoustic fans.
