I only can speak of my experiences and from what I see from my friends and colleagues. It happens quite often, that I have a lot of opened tabs in edge. Some sites are opened to revisit later (for information purpose or stuff to buy, etc.).
It would be a nice feature, if you could right-click a tab and select [remind me later] -> [10min | 30min | 1h | 6h | tomorrow]. You could get a push notification to revisit the tab/website or the tab could light up somehow.
