When creating a new issue, it is time-consuming when the issue relates to a version not currently added to the repository. One has to either abort the issue creation, or create it with an incorrect version identifier, then visit the repository settings page and create a new version identifier. Then either return and correct the previous issue's related version, or create a new issue entirely.
It would be an improvement to workflow if new version identifiers could be created when setting the version. They would then be available for other issues, as usual.
