Easily add labels to an issue

Right now, it's difficult to add or update the labels on an issue. The workflow my teams has involves a Business Analyst assigning issues to developers, and then the developer adds the in progress label to indicate which items work has started on. Then, once the issue is complete, we add a label for fix deployed once a fix is out in our staging area. Once the fix has passed QA, the issue is finally closed.

Our biggest problem is that adding a label involves opening the issue, clicking edit, typing in the name of the label, and clicking save. That's a lot of work compared to GitLab where you can just select a dropdown and click to add/remove, right from the label page. Additionally, it would be nice if from the issues list, we could add labels to all selected issues (we have a few corner cases in our workflow that would make easier.)
