General suggestions from a first-time user

Suggestion: Doc sidebar menu should not scroll with page.
Reason: There is a lot of jumping around between and this makes me lose my place.

Suggestion: Combine these four categories on the sidebar into one alphabetical Components: Elements, Collections, Views, Modules.
Reason: I've been doing a lot of what category is Segment? ::scroll up and down:: because I don't entirely understand the technical differences yet (and tbh, don't really care to learn at this test-driving stage).

Bug? And not sure if this is a chrome 54 bug or semantic ui, but Find in Page would highlight the sidebar menu item, but not scroll it into view. (When sidebar is off-canvas, things work as they should.)

The combination of all that has added some pain to getting up to speed.
