TriliumNext/Trilium ? reverse-engineered prompt

Build me a cross platform personal knowledge base app like Trilium Notes.

I want an app where I can organize notes in a deep tree, put the same note in more than one place, and jump around fast with search and easy navigation. It should have a rich editor for normal text, tables, images, math, and code with syntax highlighting, plus note history so I can go back to earlier versions. I also want tags or note properties for organizing and querying things, a dark theme, and a clean interface that works well on desktop and on touch devices.

If it makes sense, add syncing with a self hosted server, note sharing to the web, encryption for private notes, and import and export for Markdown and Evernote. Include a few visual note types like mind maps, relation maps, and sketch style canvas notes. Please make it feel polished and usable for managing a very large collection of notes, and look up current docs online if you need to.
