On my Mac, I can do the 4-finger swipe to check my full-screen notes. Usually I have a folder structure like notes/2019-10/2019-10-21.txt. If I want to tag things, I'll just write #idea #work somewhere in the text file.
Then easy to search with Sublime or whatever tool you want. I also like this approach because it's future-proof. Just a folder full of text files.
Curious how others are handling this same workflow.
Expect to continue updating/referencing it for decades to come, bar some calamity.
It's a sprawling mess, so I rely on search to find what I'm after.
I reference it often -- it's like an extension of my brain.
Similarly, several years ago I added a keybind to my .vimrc that, by typing ",a" I'm moved to the bottom of the file and today's date with a separator line underneath. My leader key is "," and I mnemonically associate "a" with "append".
The earliest date recorded in it goes back to 2006 and is about 300KB in size. I still reference and add to it on a regular basis.
Oh, and one more thing: my Markdown documents are normally R-Markdown documents, so I can incorporate calculations and graphs as needed. (Also, R-Markdown has a nice metadata section for document title, author, date, etc.)
I find this a terrible workflow problem. As often a change to code requires a small or large change to documentation that is best bundled in alongside.
For personal agenda I use Apple Notes with basically just a huge list of things to do and events that are about to happen and I curate that list more or less non stop during the day. If something comes up and I'm with people and don't want to be rude and spend too much time on the phone editing things to be in the right order and have all the relevant info captured with them, I just plop a line at the top of the note knowing I'll groom it later.
