Creating a sidebar
To create a sidebar, first use the customizer - create - sidebar. The name you put is the name that shows up only in the Leaf Customizer. Yeah that's it :3
Create Text
Every line of text has 5 frames that you can edit and a tick rate (1-20). You do NOT need to fill out any extra frames unless you want animated text.
The biggest use of a sidebar is for scoreboards! Remember you can add formatting if you want to display a players name / score / rank / etc.
