Ads app feedback

The Ads app is nice but needs some critical improvements to be fully functional:

1. Categories need a better UI separating main categories from subcategories. The user is presented with a long, unsightly list making it impractical to have many categories.
2. Location needs granular configuration, where we can set specificity (i.e. just City and State instead of whole address)
3. Ads location search and browsing filter should include radius from set location to see nearby listings. Additionally, it would be great to have visual map browser with thumbnails of listings on the map.
