Feature Ideas for the List App

@list is a wonderful community and a darn-near perfect app. Here's my unsolicited $0.02 as a web developer for small improvements. I'm curious to hear your thoughts or suggestions.
  1. Top-Level Categories
    The keyword search works really well, but wouldn't it be nice to browse lists by genre, like "humor," "satire," "travel," "self-help," "how-to" etc? Listers could self-categorize their content.
  2. List Locations
    We could also tag/search lists by city, state, country ... helping to create local communities as well as build travelogues for visitors, etc.
  3. A contextual "actions" menu on people, lists and comments
    I have trouble remembering when to swipe, tap, tap-hold and when to double-tap.
  4. In-app Audio/Video
    YouTube or Soundcloud links could play within the app without having to leave
  5. A "playlist" list
    Maybe lists with multimedia content could have a PLAY button so you can watch/listen to the entire list
  6. Web embed tool
    Those of us who run websites would love to promote the amazing content here on our sites or blogs (i.e. Facebook, Twitter and Instagram's embedded posts)
  7. Blocking for spinoff lists (by original title)

  11. We can tag locations now.
    Sort of, at least.

  12. That little location arrow. Click it, then you probably have to go to Setting and turn on location services. Then...tada!
    You can't use your map exactly, but you can search for nearby places. I'm not at a pub, but that cool pub is nearby. Also, good beer.
