Never worked with any note taking apps except for Vim with customized snippets and rudamentary helper scripts.
While such an app seems very appealing, I haven't seen any of them featuring the useful stuff, such as pluggable editor (in my case Vim or NeoVim), template support (day journal, meeting, README etc...), rendered fields (e.g.: today, author, or arbitrary values), support for pandoc rendering, doc metadata management (tags, keywords, related docs, links) or markers in text eg. @TODO etc... (idea being to aut. create lists of paragraps with such markers)
What's the point of a note taking app that provides help with editing single docs and maybe with rendering to HTML, but doesn't help organizing and remembering stuff?
