Gmail Buttons is a free Chrome add-on developed by Aaron Kao that enhances the functionality of Gmail by adding custom tags and gifs through the use of buttons. With this add-on, users can easily insert pre-defined tags and gifs into their emails, making communication more interactive and engaging.

One of the key features of Gmail Buttons is the ability to add custom buttons to the Gmail interface. These buttons can be personalized to insert specific tags or gifs with just a single click, saving users time and effort. Additionally, the add-on provides an "auto" feature that automatically submits an email with just one click. However, users are advised to exercise caution when using this feature to avoid unintentional email submissions.

To add buttons to Gmail, users can follow two different methods. The first method involves navigating to the chrome://extensions/ page, locating the Gmail Buttons plugin, and accessing the extension options to configure the buttons. The second method is to simply click on the icon located on the top right of the browser and select options. After configuring the buttons, users will need to refresh Gmail for the changes to take effect.

The Gmail Buttons add-on has received updates to improve its functionality. In version 2.000, the options page now saves the state, icons have been added, and bug fixes have been implemented. In version 3.000, users can now delete individual buttons in the menu. The most recent update, version 3.100, released on March 4, 2020, addresses a split view issue caused by internal Gmail updates.

Overall, Gmail Buttons is a useful add-on for Gmail users who want to enhance their email communication with custom tags and gifs. It provides a convenient way to insert pre-defined content into emails, improving efficiency and making messages more visually appealing.
