I would love to replace my OmniFocus setup with pure obsidian, but the one thing I am missing is the “rapid capture” keyboard shortcut, from anywhere on my Mac I just hit some key combo and a little text box appears and I type on a task and boom, it’s saved. I use this to keep track of things I’ve done, things I need to do and so on (helps with billing also since they’re timestamped). Anyone come up with something similar for obsidian? I could write a little app that throws a line into “inbox.md” or so I suppose..
