1) there's an option in the settings (Build tab) that allows you to always use the default suggested name, and although this is what works for you, it isn't the best option for most people.
2) when there wasn't icons/buttons people complained that they had to dig in the menus to find what they wanted, again it's down to what you like not being what most people prefer.
3) not even a slight chance of happening, since a program that doesn't stick to its original name always loses users in the transition. This could be said from DVD Decrypter, whose burn engine was made batter and turned into ImgBurn, yet a lot of people still use the former program for burning. Some people (you can see many thread in this very forum about this) don't even bother to update ImgBurn purely because they think the newer version has no improvements and/or is different from the old version (/myrant)
