(ex.: `feature/#-Title`) This would allow to follow some standards/workflows such as GitFlow/GitFlow (AVH Edition) to work directly with their start/finish/delete command logics plus having a flexibility to use any other flow and to link with the issue within GitLab. ### Proposal Add an option in the settings of the project (Maybe, if possible, potentially defaulted by the a same option in the admin settings) to set a prefix and/or suffix to new branches created with the `New branch` button in the issue page. ### Documentation blurb If you are adhering to the GitFlow branching model and want to link your branch with an issue, you can set the prefix of the `New branch` feature from the issue so it will works properly on both GitLab for the issue and your GitFlow configured branching model. Set it in the project and/or admin settings.
