When creating several projects a day, sometimes it can be a real pain to select all the schemes per project. What I am suggesting is that Atlassian create a Project Configuration Scheme system that you configure all of the following information:
Issue Type Scheme
Issue Security Scheme
Field Configuration Scheme
Issue Type Screen Scheme
And allow you to assign all of those to a project in a single selection of Project Configuration Scheme from the project admin screen. That way you can setup many projects quickly.
