I'm delighted to announce a new table sidebar! Open a project page— you'll see the runs table has moved into an expanding sidebar. Quickly turn on and off visualized runs, and expand the sidebar to see the full table of all your experiments.
Click the colored dot next to a run to customize its color in your workspace. Here's an example where two runs on my graph are both purple. I switch one of the lines to red, and now I'll see this run as red on all graphs on the page. This only applies to my personal workspace, so anyone else on my team won't be affected by my custom color choices.
