The Windows 10 April 2018 Update is here, and includes a bunch of features designed to make your screen time more efficient. The update's headline addition is Timeline, which lets you go back in time up to 30 days to find the things you've been working on. It works across devices, as long as you're signed into your Microsoft account, so you could do some research on your phone while you're out and about, then pick it up on your desktop at a later date. Another key feature is Focus Assist, designed to eliminate the zillions of web-based distractions that get in the way of productivity. Turn it on and it'll block emails, updates and notifications, turn it off and it'll give you a summary of what you missed. It's customizable, so if you're waiting on a specific email you can choose which stuff can break through.The update is available now for free.
