Microsoft has announced a major update to its List app as it promises to deliver “double the speed, half the hassle.” Without going into details, the company says that new listings can load in half the time thanks to various optimizations done under the hood. In addition, user experience (UX) is also getting a new look. For example, the “Group By” button has received an update.

Lincoln DeMars, principal group product manager at Microsoft List, wrote a blog post on the Microsoft Tech Community Forum. He writes:

These performance updates are paired with a host of optimizations for the user experience that puts people, content, and essential actions front and center.
Apart from speed improvements and UX updates, the new listings are getting updates in other areas as well. These are given below:
