Simple outlining template?

Does anyone have any simple outlining templates they’re willing to share? (similar to mind node pro-style or my thoughts). Ive had issues with large outlines in omni graffle → hard to fit them well for printing and/or finding a good text setting/object layout setting.

Ideally, it would be great to select a subtopic (with its children) and apply a different diaphragm layout vs. The main layout (see the attached image for an example).
