• Clarify the current and target architecture
• How to improve performance: what are the key points to improve?
• Improve tile subdivision mechanism and fetching strategies
• Add perf regression tests
• Improving support for the Mapbox Vector Tile and Style specification (performance and visual alike)
• Support for the Mapbox RGB terrain format
• Experimenting with 2D vector accelerated rendering
• Migration to TypeScript (there is a lot of work here ;))
• Experimenting with "proof of concepts" with your data and use cases
