On version 8.0 you have the 2-Stage Deploy option and configuration on the Environment Configuration:
It would be nice to have one setting available when you are about to publish one solution to ignore the 2-Stage Deploy for the respective solution or vice-versa.
This would be very useful if you only want to apply this feature for a specific solution or project.
It would be nice to have a setting per solution to apply by default the setting defined on the environment configuration, or to set for always make use of the 2-Stage Deploy or to never use the 2-Stage Deploy for that solution.
