It feels like a vim plugin. It definitely feels like org-mode can do this.
A few years back I had a little command line tool where I could log things quickly - it was like syslog for humans - but with #hashtags for projects or clients, and then a small tool that would work out how long I'd spent on different things. It required me to write a log every time I finished a task or a pomodoro. I might resurrect that, but having an open file has been cute for me for quite a while, and then I can go back and copy/paste what I need to draft docs and so on.
I do think "note taking" as an app is actually under-served. There's lots of wiki plugins, org-mode, tons of "productivity tools", but actually a single app that lets you just write, then helps you with review (and timestamps, contexts and so on are essential to that), and then figure out actions/todos and gives you seamless interaction with those, and integration with 3rd-party tools (I don't want to copy and paste between vim/emacs/JIRA/asana/notion/trello/apple notes/calendar reminders/outlook tasks/whatever), would be very, very neat.
