I have added some tags, but forget to push them to the remote. There's at this time no way to see these missing tags, as far as I can see.
If there's no easy way, could you please add this to the feature requests?
Thank you
-- Edit:
Why: These tags are used in an automatic build system. And when someone forget to push them to the remote, the build breaks... If everyone had a visual clue for missing tags on the remote, this would save some time for resolving those kind of errors.
For a possible solution, maybe you could add it this way: http://stackoverflow.com/questions/11308298/how-to-list-unpushed-git-tags
