Thank you for trying out changes! The use of negative space tabs idea is clever, and does give more context to their purpose. The minimalism of the single line previously was clean, at least for those who know its there, but that subtlety might've been what made it easy to overlook. Currently in the above tabs, the text might benefit with some extra vertical breathing room.
