To create a Custom Category, select the Categories tab, and then click 'New'. You can change the name, if you like.
Next, select the Buttons tab and click 'New Button'. Click the little '+' next to your new button and select 'Categories'. In the dropdown, choose your newly created category.
Select your custom button again, then check the 'Always Show' option and the 'Drop' option. This will allow you to drag and drop items or spells onto the new button which will add them to your custom category.
