By default, all newly created issue types are automatically added to the Default Issue Type Scheme. However, we have some specific issue types for use with non-global projects that need not be shared amongst all other projects. (Most of our projects are using the Default Issue Type Scheme for simplicity.) It would be nice if either:
1) the "remove" functionality was added to this scheme; or
2) newly created issue types never even made it to the Default Scheme.
