Thanks!

About point 2, let me clarify. I know that I could either pick a pre-existing category or type my own freeform text. I was trying to make the decision of which to go with based on what pre-existing categories existed. To make that decision, I wanted to be able to see the full list of categories. I was able to see that full list and make my decision, but in an awkward way. Hopefully that makes sense.
