If there are certain icons (or groups of icons) that you’d like to save for future use, you can add them to your Favorites, which is your own personal collection of useful icons.
To add an icon or a group of icons to your Favorites, follow these steps.
Place the icon or group of icons you'd like to save onto the canvas.
Select the icon or group of icons you'd like to save. You can do this by clicking and dragging on the canvas across all icons, or by pressing shift + clicking on each of the icons you want to save.
Once you have your icon(s) selected, click the Favorite button in the top toolbar or right-click the selected icon(s) and click Add to Favorites.
Using Your Favorites Later
Icons that you save to your Favorites can be found in the Favorites tab on the left side of the screen (a notification will appear on this tab to let you know you've saved a new Favorite).
To use your Favorites, simply click-and-drag onto the canvas like a regular icon.
