Global labels and copying labels from repo to repo.
The ability to copy labels from one repository and optionally overwrite the current labels with the labels from said repository would make for a very convenient feature.
It is not necessary or critical to functionality with gitlab, although I see it more as a convenient feature in the case of custom colors or a large amount of labels that are used cross-project.
This could be implemented as a UI in the label editing page.
Edit 06/09/2015 (dd/mm/yyyy):
Along with the above, it would be very useful for individuals and organizations to each hold a collection of global labels that can be used for all projects. IE: A global label "bug" in an organization- all repositories in the organization can use the label "bug".
