"Create new branch in fork from upstream project's issue"
I find that the new "create New Branch from issue" feature a really good addition to the already very good gitlab product, We are keeping up with gitlab's monthly updates as part of our workflow and are really happy with the progress the product made so far.
In our git workflow we give developers reporter access to the repository and have them develop in their private forks then create a MR targeting a public branch, so it would be good if they could create use the New Branch option to create a New Branch in their own forks.
We also use a special naming convention for the feature branches so having the ability to update the new branch name while creating it would be very welcomed.
