This was not intended and happened just because title is kind of generic. Since there is no perfect solution for ICS yet without modding, it is good that alternatives are appearing so everyone can pick solution that works best for them.This application is pretty similar to HideBar (http://ppareit.github.com/HideBar/), an application that has been in development for over a year. It contains an intuitive user interface to hide/show the systembar.
I find the development of customizing tools like GMD very good. But as a developer you should not use the same name. This only leads to confusion for existing users.
