I hear you. I often outline in Mellel, my word processor of choice. The Outline pane, like what Word calls the Navigator (I think), is my topic list.I used Trilium Notes for over a year as my second brain. After setting it up similar to scrivener it puked on itself and I lost way too much work. Even it's backups were corrupted. From that point on, I have reverted to the tried and true LibreOffice.
I played with LogSeq for a while, and there were things I liked, but I just didn't stick with it.
My top level heading (auto-title, in Mellel-speak) inserts a leading page break, so each top level heading starts with a blank page.
I just love blank pages. They are to me what fireplugs are to dogs.
