## Install tests
 * install a **previous version** on a clean machine (a clean machine doesn't have the `%localappdata%\Microsoft\PowerToys` folder)
 * open the Settings and for each module change at least one option
 * open the FancyZones editor and create two custom layouts:
    * a canvas layout with 2 zones, use unicode chars in the layout's name
    * one from grid template using 4 zones and splitting one zone
    * apply the custom canvas layout to the primary desktop
    * create a virtual desktop and apply the custom grid layout
