I use it almost daily when in bed and thinking of some project or the other—I like to think in text—but don’t want to bring up my notetaker and getting even more distracted.
And I often get friends and family open one up while troubleshooting their problems. What else would I use, Notepad?
Ultimately, why not? Why do people make little standalone tools like this? For fun, probably. Or because they can. As a learning exercise? And when it has no cost to the developer to maintain, or the user to use. Why would I even try to second-guess their motivation?
I actually used a web text editor when I did Nanowrimo one year. It was great because I could use any computer (desktop, laptop, even my phone) and just type. I didn’t need any fancy tools, and performance wasn’t a concern because I wrote scenes in separate documents.
So I totally get it.
That said, I almost never use these apps for quick notes. I forget the URL, don’t feel like looking up a bookmark, etc. I’m a vim user normally, so I just open a terminal with vim. It’s great, and it works on all my machines (macOS for work and Linux at home), with the huge exception being my phone, but I have a simple notepad app for that (great for meeting notes, grocery lists, etc). But if you like a notepad, I’m sure you could keep the tab pinned and make good use of it.
Yeah, as pinned tabbed. Very much so. I actually like them specifically because I can forget about them. I use them like someone would use a napkin in that classic Hollywood trope sense! Just to work something out and then forgetting about it, except, if needed, I can open up the tab again and copy over stuff to my actual notes later!
