Just Tweet Button is a Chrome add-on developed by KaoriYa. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This free program allows users to easily tweet the current site they are browsing without any additional features.

The main purpose of Just Tweet Button is to provide a straightforward way to share the title and URL of the current webpage on Twitter. The add-on is designed to be minimalistic, focusing solely on the tweet functionality without any extra frills. Users can simply click on the tweet button and a new tweet window will open with the pre-filled site title and URL.

With version 1.1, Just Tweet Button has made a couple of changes. Firstly, it has added the "tabs" permission to ensure compatibility with the latest version of Chrome. Additionally, the program now uses a "»" prefix for the page title, although this will be configurable in future updates.

Overall, Just Tweet Button provides a quick and easy way for Chrome users to share webpages on Twitter without any unnecessary features or distractions.
