SlackDeck is a Chrome add-on that allows you to display Slack channels in a column format. With this add-on, you can easily add, rearrange, and delete channels as columns, giving you a more organized view of your Slack workspace.

One of the key features of SlackDeck is the ability to choose from four different column widths, allowing you to customize the layout to your preference. Additionally, you can save the current state of your columns by clicking the save button, ensuring that your layout is restored when you reload Slack.

To set the names of your columns, simply use the input box at the top of each column. This makes it easy to categorize and label your channels for quick reference.
