Considerations

• @mle had concerns about adding tabs in the past to disclosures and some recent thoughts on this from Slack
  • @trevorpierce tabs within a disclosure should be avoided for the cognitive load they can add. If I'm opening a disclosure, I'm already keeping the clicked item name in memory, so the choices presented have some context. If we add tabs as a way to show and hide different facets of that context, we're doubling or tripling the pieces of information the user has to remember just to make an informed click. This cognitive load stacking increases significantly for screen reader and voice command users.
  • (in context of vertical tabs) @jeldergl I don't consider tabs to be navigation. They're content-switching rather than wayfinding. Changing the view rather than selecting the destination.
• @alyssatrinh Idea: What if we condensed the "Open with" into a dropdown, like you did for the Download options?
