I'm guessing it is only early days. But a few added features that would be useful would be:
- More aggregations that already exist in standard visualizations such as cumulative counts
- The ability to convert a lens result into another visualization so more advanced features can be applied to it
- The ability to remove a layer if no longer desired.
- Have layers able to overlay each other with maybe an opacity controller for each layer
- Suggestions adjust to the size of the window or at least are scrollable
Like the direction though.
