Next steps - planning for v4
We're planning for v4 to be a major next step in the evolution of Data Populator. Our thinking currently revolves around:

- A brand-new UI/UX to eliminate the need for complex syntax in layer names
- A unified platform for managing and manipulating data sources to make finding the right data easier
- A more stateful approach to selecting data sources for particular layers/groups

These are the core ideas but we'll update this issue as we get closer to v4 and the feature set is defined. 

We'd love to hear your ideas and suggestions!
