GitHub-Connect-Team Explorer clone link while another one is processing馃槈 Love this extension so much.
Thanks @BOT-Man-JL - this indeed sounds like a bug!
It looks like this can't be done on VS2015 as IGitRepositoriesExt.Clone doesn't return the progress of the clone operation. However I should be possible on VS2017 via the new IGitActionsExt.CloneAsync API.
