+ VRay is the flagship product and it will always get more attention: you are paying less for less. Fair deal.
As Tom mentioned there's a lot of different users with many different requests/priorities so perhaps it would be beneficial for the Corona team to archive the old "most requested features" thread (now almost 12 years old) and start the polls fresh to find out what the majority of users would find beneficial in their modern workflow?
With regards to development feeling like it's slowed, I imagine it's more a case of the product maturing and the shiny "big features" are already in place. A few years ago I remember seeing FStorm users getting excited about something like a masking render element - something basic that many other renderers already had.
Also we shouldn't complain about Vray having more development without knowing how big its user base is compared to Corona's.
Note: By "new features" I always meant "new features" and/or
improve existing ones.
Resetting the "most requested features" ranking would be nice.
Update: It would be nice if Scatter, cosmos, nodes, Vantage, library, etc is all sold as addons to the core Corona. I'm assuming it's not so good for business, but it would be nice I think.
