What is Timeline?

The time I spend in front of a screen spreads across various devices: my dev box, Surface Book, phone and Surface Studio. I love using these devices, what I don't love is when I have to try and pick up from where I was last week. What files did I have open? Where was I in those files? Which device did I last use them on? All this just adds to the Monday morning blues. I know most of you will say "check your recent files!" but I'm one of those people that opens a lot of files across various apps and devices in day.

What I want is the ability to see my activity across my devices in a single place that's easy to digest, like a browser history for my application activity. I would love to search a keyword that ties this experience together and be able to continue my activity in the right app, at the right place.

Well, guess what? Timeline is this experience! To try it out you'll need a build of Windows greater than 17074 (currently an Insider build at time of writing).

I should also mention that because I log into Windows with my Microsoft Account (Hotmail/Outlook/Office 365) I get a enhanced experience because certain aspects like OneDrive and Office leverage the Microsoft Graph to enrich my Timeline so I can use any of my devices to continue my experience.

All I have to do is press Windows + Tab key or click this button in the task bar:
