I couldn't find a way to add comments to this file, so made some edits directly. I hope that's OK. My notes:
- my edits were mainly trying to simplify the structure so that someone reading or skimming the TOC could get a quick grasp of what's there - I hope I didn't move things around too much!
- instead of "Status" should the subheading under "Outline vs fill" be "Exceptions"? Better yet, could we remove the subheading and just have a sentence like "and exception to this rule is to indicate status or completion…"?
- "Icon states" - I think i need to see it with the examples to give better feedback on this section
- I put icon names in code blocks to make it clear they're icon names, not sure if that's appropriate
- note to self: in the content UI guide, we should state how to refer to tabs, buttons etc. within the UI (and also in docs guides)
- is it too much to show the icon referred to in the "Specific icon usage" examples?
