Hi @mhiltner 

You are correct, simply clicking the experiment icon on the right will create an experiment. Why is this the default behaviour? It's cluttering the workspace, creates unnecessary experiments just by creating new notebook, because if you do not close the experiments tab before closing the notebook, then it will auto-open on any notebook you open after. 

Please fix this, this is more than annoying, considering you can't delete the experiment without deleting the notebook.
