Starting with Filter Forge 13 filter authors can add separators on the Settings pane to divide a long list of controls into groups. To add a separator, open Filter Editor, select Filter > Order of Controls, and click the Add button:

You can have up to 100 separators in a single filter and change their order to your liking.
