Currently, Sourcetree offers support for GitHub, such as looking up repositories and creating pull requests. However, the URL for GitHub is set to 'https://www.github.com' and cannot be changed.

If possible, those features that use GitHub should also work with GitHub Enterprise, which is an internally hosted version of the same platform. It would be nice to be able to change the GitHub URL to point to a company's internal GitHub Enterprise server rather than just the public one.
