One of the already announced features “Timeline” that didn’t make it to Windows 10 Creators update will soon arrive to Windows Insiders. In the mail sent to millions of insiders, Microsoft’s EVP Terry Myerson confirmed that both Timeline and Sets features are arriving soon in a new Preview build.

We posted about Sets feature and the official demo video here. Timeline feature enables one to go back in time and access what one was doing.

Today people work and play across multiple applications, platforms and devices and we want to make this easier and more seamless for our customers, so they can focus on what’s important – creating and getting things done. Earlier this year at Build, we showed you Timeline, which allows you to jump back in time, making it easier to find the files you’re looking for. A visual timeline is integrated directly into Task View so you can easily move back into files, apps, and sites as if you never left. We’ve heard strong interest in this feature, and we’re pleased you’ll see it in the next WIP build going out to the Fast Ring.1 We look forward to hearing your thoughts on this experience.

Microsoft has also announced that not everyone will get Sets feature at the same time.

With Sets specifically, we’ll introduce a controlled study into WIP so that we can more accurately assess what’s working and what’s not. That means a smaller percentage of you will initially get Sets in a build. It also means that some of you won’t get it at all for a while, as we compare the usage and satisfaction of task switching in Windows for people who have sets versus people who don’t. Eventually everyone will get Sets — but it could be awhile.
