   Great feedback. A few other notes:
   * loading different dimensions could be parallelized on the backend to make things faster
   * cascading filters (where the list of values is based on a previously selected filter) are great for hierarchies (think: continent->country-> city). Currently it's doable only by having multiple FilterBox slices where one refreshes based on the other, but not the other way around (you can make the first filterbox immune to filtering). It's pretty common for BI tools to know about hierarchies and we could add support for that in our semantic layer and cascade things accordingly based on that.
