BTRCollectionView is a port of
PSTCollectionView to the Mac. It is quite buggy, and animations are known to have issues. This project has been deprecated and will no longer be developed further.
This repository is completely unsupported. If you use it, please don't expect us to provide any support.
Users wishing for a stable, fully-featured collection view for the Mac can look for
JNWCollectionView, which will be released in the near future.
Use in a production app is not advised at this time.
