Old Tumblr Dashboard is a Chrome extension developed by hderandall, which brings back the classic look of the Tumblr dashboard. The extension was created to satisfy users who were not happy with the significant changes made in the latest update. With this extension, users can enjoy the old Tumblr dashboard experience, with the exception of the drop-down for blogs, which remains the same.

The extension has been updated twice since its release. Version 0.2 adjusts the main post container width to ensure it is not overly wide, while version 0.3 fixes the post type selection width, which was broken with the last update.

Overall, the Old Tumblr Dashboard extension is a great tool for those who prefer the old Tumblr dashboard layout. It is easy to install and use, and it is completely free. The only downside is that it does not revert the drop-down for blogs, but this is a minor inconvenience that does not affect the overall functionality of the extension.
