Is cutting and pasting a tough one? Maybe the big word scared ya? I could have written open, with no change in meaning.
If it's not clear I didn't sign it in the technical sense, no one would know what to do with it, there's not a widely supported standard for that. These were business folks who wanted a png/jpeg image of the form with my scribble on it.
An image editor is perfect for that it turns out, and it takes two steps, three if you count save.
Is any normal user going to do that? Why the hell should I have to open a image editing app to sign a PDF?!
Why has no Linux PDF viewer added signatures as an option so far?
This is why I left Linux for MacOS
