Instagram has made saving groups of photos more appealing through a new collections tool.
Until now, users could only bookmark favorite photos for later. Now, Instagram makes it possible to create and name new collections of bookmarked posts that are batched together. This applies to both new and existing posts. Instagram says people can cultivate as many collections as they wish, which can be used to tag and manage types and/or styles of photos, as well as the contributions of select people or groups.
Collections will remain private to the person who created them. The new collections feature is rolling out to the Android and iOS versions of Instagram over the next week. Instagram is free to download.
