Chew shutting down is quite unfortunate as it was the only serious alternative to Slipmat I know that was truly developed for DJs. This does not affect Slipmat in any way, other that maybe we have now more DJs coming in – who we all welcome to the community with open arms! 
We have an active development plan which moves on like it has so far. The summer months were slow development-wise because my personal commitments and due to low participation from other members of the community. Now that the everyday life is slowly starting again, I believe things will get rolling a bit faster in near future
It’s hard for me to do absolutely everything so community help from all members is very welcome. Helping newcomers here by tutoring and answering questions is a great place to start and all feedback and bug reports about the current features are very welcome. And new DJs interested in joining the Slipmat family, you should start here: How to Get a Beta DJ Invitation
Cheers!
