I've listed things that I want to implement in Chronicle Map sooner or later:
https://github.com/OpenHFT/Chronicle-Map/milestone/1
However I have very little time, so doing that all myself will take very long time, or forever.
So please express your special interest in a subset those issues, this will make me more likely to start implementing those features sooner.
Of cause helping with development is very welcome, please contact me if you are interested in developing one of those issues yourself. And it will definitely be much faster than if you wait until I will implement it.
