Android/iOS: If you save a lot of posts using Instagram's bookmarking feature you've probably lamented the fact that those bookmarked posts just pile up into an unorganised list. Today, Instagram announced that it's rolling out a means to actually organise those posts.
Instagram introduced the bookmarking feature a while ago, but failed to include any means to organise those bookmarks. So, they're adding collections. If you want to create a collection, head to your saved posts (the bookmark tab on your profile page), then tap the "+" button. To send a post to a specific collection, tap and hold on the bookmark icon and you can then choose the collection to send it to.
If this all sounds a heck of a lot like Pinterest, you're right, it's basically identical to Pinterest, with the exception that all of your collections are private. The feature is rolling out for Android and iPhone this week.
