That's a good idea. If they implement it, I would however suggest putting a limit on to it - perhaps only let you see the news within the last week/month.

This seems to go against the principle of the product (see endless scroll)

If you missed a day of news, whatever was really important will re-surface in today's news (major world incident)

Otherwise, perhaps what was missed is noise!

We've Time Travel feature coming soon to both the web and mobile apps. It'll allow you to browse the stories from any date since we started aggregating news ;)
