This is something I really like seeing expanded in Windows 10.

The Timeline feature in Windows 10 made its debut with the April 2018 Update and it takes advantage of the Microsoft Graph to display various activities across all of your Windows 10 devices that use the same Microsoft Account.

At this point, the vast majority of the content within the Timeline display is from Microsoft apps but the programming options are available to app developers if they want to incorporate their own apps data into the Microsoft Graph. That means it would also be listed in the Timeline view on Windows 10.

As noted by OnMSFT, apps that you browse in the Microsoft Store will now appear in the Timeline on your devices.

Of course, any data that is displayed in the Timeline will also be discoverable when searching within the feature. This alone adds a capability the Microsoft Store doesn’t even have – the ability to review apps you have previously browsed in the Store.

Like I said at the top, the more data from the Microsoft Graph that is integrated into the Timeline, the better this feature becomes.

Now to see more third party apps take advantage of Timeline.
