"Have I bookmarked their tweet?" is a Chrome extension developed by standot33. This free extension falls under the Browsers category, specifically the Add-ons & Tools subcategory. The program aims to offer a quick preview of all your saved tweet bookmarks from a specific user on Twitter. By simply clicking a button, users can easily check if they have bookmarked any tweets from the specified account, streamlining the process of revisiting saved content.

The latest update, version 0.0.2, promises a smoother experience by introducing a loading status indicator immediately after activating the extension. This enhancement aims to provide users with a more seamless interaction with the extension, making it easier to navigate and view their saved tweet bookmarks.
