My first dive into Linux, using Ubuntu in 2007, burned this image into my mind for all eternity. The non-microsoft save dialog. What was this sacrilege? It was exciting. It was different.
Then I discovered that I couldn’t do any file management from inside of it, like I could do in the Windows one. The best you can do is create a folder — you can’t rename anything, or even right-click a folder and open a proper file manager dialog (to save you from having to navigate there manually anyway). Woe to you every time you save a file or create a folder with the wrong name.
