Have project-universal environments
E.g. in account settings have the option to set environment variables. Means you don't have to enter the same docker hub password for each project.
Sorry for the late response here but we've added organization level environment variables. If you add an environment variable (such as docker hub username & password) to hte organization every project under the organization will be able to read it.

+1 This feature would be great and would be a timesaver for us.
