Something I notice a whole lot is that people tend to always include 'OS' into their operating system names, and I dont mind, but you dont have to always add 'OS' to the name to make it a good operating system. Look at Windows, PineDesk (Scratch-based OS), Ubuntu, and many more, they dont have OS in their names! Keep in mind, i dont really care much about the name, but it's never bad to be a bit different than others. (Also, GUI is VERY important for your operating system; it defines it.)
