I also use a small CLI program to loosely manage them. Basically, it just creates a new file in a predetermined folder and opens it in my text editor, which I've bound to a global shortcut, so it's just one keypress for me to start jotting something down.
Well, and then it also allows searching through all note files and things like that.
Not a fan of it using Electron and a proprietary license.
But I also actually like this workflow. Being able to note things in my regular text editor with the keybindings I know, is quite important to me.
Well, and an even more personal preference, but my way of using a desktop OS involves a lot of workspaces, so the global shortcut to summon a new editor window on the current workspace actually gets a lot of use.
