 * `autoReadOnlyDisabled` - text/code notes can be set automatically into read mode when they are too large. You can disable this behavior on per-note basis by adding this label to the note
 * `cssClass` - value of this label is then added as CSS class to the node representing given note in the tree. This can be useful for advanced [[theming|themes]]. Can be used in `template` notes.
 * `iconClass` - value of this label is added as a CSS class to the icon on the tree which can help visually distinguish the notes in the tree. Example might be `bx bx-home` - icons are taken from [boxicons](https://boxicons.com/). Can be used in [[template]] notes.
