Gmail Conversation Reversal is a Chrome add-on developed by Bart Solutions. It is a free tool that allows users to reverse the display of emails in Gmail threads, showing the latest email at the top. By default, Gmail conversations display the oldest email first, but with this extension, users can easily reverse the order.

This add-on was inspired by the "Gmail reverse conversation" extension, but Bart Solutions has made improvements and fixed some issues to make it more reliable. With Gmail Conversation Reversal, users can have a more convenient and intuitive email viewing experience in Gmail.

Please note that this add-on is only compatible with the Chrome browser. It falls under the category of Browsers and the subcategory of Add-ons & Tools. The source code for Gmail Conversation Reversal is available on GitHub for those interested in exploring it further.
