@progrium - 2 panel design linked below. i ultimately removed the vertical outline lines because they compete for attention and aren't really serving a purpose, especially when there are multiple panels. i can show you the versions i tried when we chat this week. https://www.figma.com/file/bGzEZo0NYHhWGJO95kwF3p/Treehouse-App?node-id=22%3A185&t=AmB4MWNqlPrN0Mrd-1
