Slack "Also send to #Channel" Default On is a tiny Chrome extension developed by Jeppe. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension aims to simplify the process of sending messages to channels in Slack by automatically checking the "Also send to #Channel" checkbox.

When using threads in Slack, users have the option to send their messages to the channel as well. However, by default, this checkbox is unchecked. With Slack "Also send to #Channel" Default On, the checkbox is automatically checked, making it the new default setting.

By enabling this extension, users can save time and avoid the hassle of manually checking the checkbox every time they want to send a message to the channel. It offers a convenient solution for those who frequently use threads in Slack and want their messages to be visible to everyone in the channel by default.
