From the developer:
HideBar is a Mac menu bar utility to show and hide system and hidden files without using the terminal on OS X Yosemite. By using HideBar you can experience a clean interface as you go about your work. To view the menu bar, simply drag your cursor up to the top of the screen and hold it there for a second.
