Onenote as it was on the Mac back in 2015-6, with its rich text canvas and table support, with...<p>1. Actual WYSIWYG but limiting some parameters so pages don't inherit ghost styles from copying&pasting, like indentation or margin rules you can't change later.<p>2. Not a Markdown-first approach like Obsidian/OutlineWiki, even if it comes with live preview, since I can't style certain elements like adding color to table cells.<p>3. A well thought out layout with a clear design vision.
Instead of the overly customizable, plugin-centric approach of Obsidian, where I always end up wasting time trying to customize it to my taste, yet never getting it quite right, and where an update can break my changes.<p>4. It still allows code/markdown/txt boxes or inserted objects, like a linked spreadsheet, Python notebooks, formatted CSVs, etc.<p>5. Offline-first, each notebook in a file/folder structure of my own choosing.<p>6. Good mobile app.
