Twitter Gallery Caption Toggler is a free Chrome extension developed by Sharath Prabhal. It falls under the category of Browsers with the subcategory of Add-ons & Tools. This extension specifically addresses the issue of media captions overlapping controls when watching videos on Twitter.

One common problem when viewing videos on Twitter is that the caption or tweet displayed alongside the media can obstruct the controls provided by the media provider. This becomes particularly inconvenient when trying to perform actions like pausing, rewinding, or forwarding the video. The Twitter Gallery Caption Toggler offers a simple solution by allowing users to toggle the visibility of the media caption on the page. With just a click, users can hide or show the caption, enhancing their video watching experience on Twitter.

By providing this functionality, the extension enhances the usability of the Twitter platform, making it easier for users to interact with the videos they come across on their timeline. The Twitter Gallery Caption Toggler is a useful tool for those who frequently watch videos on Twitter and prefer to have an unobstructed view of the media content.
