Where are features displayed after they are created?
I think its important to know that essentially, Features result in modules that capture site configuration.

Fundamental differences in D7 and D8 with what Features is designed to accomplish with configuration essentially in Core.

However, if you create a feature and "write" as opposed to "download" the UI should show your saved configuration. This section of d.o gives some detail.

You may prefer to try downloading features once they are what you want, and commit them to a git repo.  Much safer and stable working this way in my experience.
