How it works:
From any file, in any project, in VsCode just press CMD + SHIFT + J, select 'Today' and it will plop you into the journal page for today with today's date at the top.
I've been keeping a 'work diary' in VS Code - tried a couple of simple notes plugins but I ended up just pinning my diary.md file in my main window... always easy to get back to it.
I think the only other QoL I have for it is the markdown snippet I created that creates the current day's date and other boilerplate data when you type 'td'. It works really well for me, and I back up to a private git repo.
