How to rename a project?

In the All Projects View, find the project that you want to rename, then in its card, click the Dotted menu > Settings.

This will redirect you to the project's settings page where the option to rename the project can be found.

Alternately, if you're already inside the project you want to rename, simply go to its Dashboard then click Settings (#1). Or you can go to Configuration > Project settings (#2). The latter you can access any time as long as you're inside a project.

Once you're on the Project Settings page, you can find the option to rename the project.
