One good way of writing and distributing Codea code involves tests. A useful package might consist of some tabs that would be part of the package for inclusion as a dependency, and other tabs for tests that show how the package works, and that it works.
Today, one could put all the tests in the Main tab. It might be of value to provide a way to mark other tabs to be ignored in dependencies, as Main is.
High value? Don’t know, maybe not.
