Agreed is a free Chrome add-on developed by Justin Shenk. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory.

Agreed is designed to streamline the process of agreeing with reactions on a webpage, particularly on the popular communication platform Slack. With Agreed installed, users can simply press the hotkeys "Ctrl/Cmd+Shift+Y" to agree with the first reaction to every post. For those who want to agree with every reaction on the page, they can use the hotkeys "Ctrl/Cmd+Shift+X".

This add-on provides a quick and efficient way to express agreement without the need for manually selecting each reaction individually. It saves time and effort for users who frequently engage in discussions on Slack, making it a valuable tool for enhancing productivity and communication.
