I would like the ability to drag and drop existing Perfstack charts/metrics after a project has been created. Keeping custom Perfstack projects updated can be tedious if you've made changes to your environment. In my case I have to right click > remove each metric individually and build the project over from scratch in order to make sure the metrics and charts are organized the way I want them. In this example, notice that "Knapp Router" is the orange line in the top chart and the light blue line in the bottom chart. The only way to fix this is to delete the last two metrics on the bottom chart and re-add them. It would be much quicker if you could drag/drop these metrics and their colors would change as you move them.
