I've just begun using Calcutta (good stuff btw). One change that I noticed is in how disabled agents behave. In v. 3 when you disable an agent you can still target specific builds to it and have them run. But with v. 4 when an agent is disabled it is truly disabled. While I see the value of being able to shut down an agent I found the ability to isolate an agent really useful (for setting up new builds or creating a fast lane for some immediate needs).
Was this change intentional? If so, any chance of getting an option to allow the previous behavior?
