Hi Zach,
Thank you for the suggestion regarding the tabs. It's always good to hear ideas and suggestions from our customers. We're actually working on a few small/quick improvements to the tabs in the left panel right now, and hope to have them out soon. We're also working on the designs for improving the way that you interact with execution sets and their results, as part of our larger User Experience project, and hope to have that completed in the first half of next year.
