GIF Bar is an app that allows users to search for GIFs and share them by dragging and dropping to their favorite apps. It is available on the Mac App Store and appears as an item in the menu bar that says "GIF". GIFs have become increasingly popular on social media platforms such as Twitter and Facebook, and both platforms have added features to make it easier for users to search and post GIFs. Twitter, for example, has a GIF search feature that allows users to search and browse the GIF library while composing a tweet or direct message. Facebook has a GIF button that lets people search and post GIFs from different services, like Giphy and Tenor, directly in the comments box.
