You can hide lights by right-clicking them (the geometry must be a group or component) and enabling Hide from Camera, etc. I'm not sure if that's what you're referring to, though.
As for the other requests, assuming you are referring to the Standalone plugin (since they are already possible with the Render Suite), I'd guess that these will not happen. Regarding resolution, please feel free to make your request known to the sales dept (through your https://portal.nextlimit.com
account), since it is an arbitrary limit. But regarding channels, this would require duplicating much functionality that's already implemented in Maxwell Render Suite, which would begin to defeat the purpose of offering the Standalone in the first place. If you need these more advanced types of features, our position is that you are no longer in the Standalone plugin's target audience, and should likely be using the Render Suite.
