From a mobile device, it can be difficult to navigate between stacked items in a dashboard. Depending on how many items you have stacked, the mobile view will either show you all the tabs, or a single tab with arrows on each side to navigate to the other tabs. Those navigational arrows are counterintuitive and hard to use on a phone; they're hard to see and even harder to tap on.
If the tabs aren't visible (which is often the case if you have several tabs or tabs with long titles), then mobile users should be able to swipe between the stacked items in a dashboard.
Would love to see this for the mobile experience!
