Adding one more tab for crate's features

[HosMercury]

I suggest adding one more tab for each crate to doc their features

after versions tab or beside !!

Right now there is no good way to find every crate feature and their usage. Organizing features will facilitate the finding and usefulness of a crate feature and how to use it.

Hi @HosMercury

can you elaborate what's missing for you?

We already have a menu template for features:

And some generated description around them:

https://docs.rs/crate/itertools/latest/features

First time to know that
Although each feature should be better documented. Right?

Yeah, that's true, which is why we added this comment:

There is very little structured metadata to build this page from currently. You should check the main library docs, readme, or Cargo.toml in case the author documented the features in them.

Also see rust-lang/rfcs#3485 which we could eventually pull the data from (or deprecate our feature-flags page once rustdoc starts generating data based off it).
