Can you explain the "primary sourcen." --
I put everything into evernote (approx 7000 notes). I switched to paperless a while ago. F.e.: my insurance documents, Invoices, Guarantee documents and more are scanned and tagged. So I can find it fast - Thtats what I really love on EN.
But when it comes to "serious" note taking: I suffer each time with the editors possebilities (Tables got better after years), but: Table of Content (like: Confluence), Inline Taggging (like: Google Keep), The way of handling Content (like: Notion.so), Smart Objects (like excerps of notes (Confluence), Emedd videos, google maps and more (like: Notion), automatically updating links and link lists), Nested Searches / Nested Favorites, Smart Searches (where I can change parameters like the date range), Annotations inside of notes (like Confluence, Google Docs), Styles inside of nodes (Headings, Toc, Lists, Collapsable Lists, Anchors, Sub/Sup-Script. The editor in fact is very basic - and copying notes from other sources like web/office offten scramble my content - so I need to fix/align it manually.
Don't get me wrong: I rely on EN, but the UI is extremely outdated by it's capabilities (in comparison to other online editors / note taking apps).
So I'm working only "static" on it, but new stuff I put elsewhere (an import it later). - So I changed my workflows to try to get around with thats what's missing in EN.
Searching - or eaven loading offline notes on Android is a pain. It takes partially forever to lead a simple locale text note.
