I agree you can overcome this, but you find yourself fighting against macOS a bit to do it.
(Also, I'm surprised nobody's mentioned this isn't a blog post... it's an ad. So of course the issues are exaggerated a bit. The ironic part is I don't think the app actually solves the problems mentioned.)
Let's be clear: if you save something in macOS, by default you get: 1. a text field with something like "Untitled" already selected, but not the extension, so if you just start typing, the extension isn't replaced. 2. a text field for tags to make organization easier 3. a Where drop-down with recent locations, favorites, drives, etc. 4. a button with an arrow pointing down next to the "where" list. 5. depending on the app, probably a format drop-down.
Friends and family who depend on "you're good with computers, right?" people like us, they get overwhelmed by too many choices. Here, macOS gives them five, only five, and the complaint is that most people ignore four of them!
Give them the larger menu by default, and it's more options to ignore. If someone is saving every single file to their Desktop (/me shudders), then they are ignoring every bit of even a small, simple UI, so giving them a more complicated UI accomplishes nothing good.
I said they're ignoring four of the five UI elements, but now I wonder how many of the files on the desktop are named "Untitled (38).pdf" or whatever. They could be ignoring all five!
But, if the person doesn’t know where the file is, Finder has a “Recent” virtual folder right a the top that’ll list all files the person worked on most recent on the top. I often use it to get to screenshots. There’s also a lot of basic operations that are there since the 1990s any power user would know.
