- Useful for longer pages
- `parser_cache_min_size` may need tuning for your specific installation (lower it if you regularly use features that are slow to parse; raise if it's the opposite)
- You may need to turn this off if it interferes with complex dynamic includes

### Changed
- Completely reworked the README to refactor out the documentation to its [own static site](https://starbeamrainbowlabs.com/labs/peppermint/_docpress/)
