How many CenarioVR developers are there?

How many back end developers are there actually working on bringing new feature requests to the product? There are a huge about of feature requests listed on this site, how likely are we do get any of them and when? Can you not share a road map or a list of features which are being reviewed / are in development / are not planned etc.

I've not used CenarioVR to create any new projects for about a year (I've only done minor editing to existing projects) but I'm a bit disappointed the community has offered so many great ideas and hardly any have made it through and we have no idea how long it might take to get much needed changes.
