I am a novice with the workflow editor. I installed it and downloaded workflows from the server. Then I created my own workflow and though: "Why do I need all the rest workflows to be shown on my local computer". So I deleted them. They I wanted to upload my workflow to the server. I believe you know what happened - all workflows on my server disappeared except one, my own.
How important are workflows for projects? Should I restore them to make my projects function properly? If so how to do that? I am using the hosted YouTrack.
