I beg you, if you are a developer of an open source app or program - add screenshots of your app to the README file. When looking for the perfect app, I had to install dozens of them just to see what the user interface looked like and whether it suits me. This will allow users to decide if the app they choose will suit them… Please, don’t think about it, just do it…
I actually know what causes most of mine, there are some nerves in my neck that get pinched/aggravated and trigger them. And for some reason, if I have multiple days in a row where I don’t get much sleep, those nerves get extra cranky. They are extra cranky right now.
I’m so so sorry! I guess, at lease, you know why. That’s something, right? Not really, but :shrug: seriously, I’m so sorry you’re going through that!
