Despite of all the fancy colorful ui, there is available out there a nice small black window, that will let you do everything you want to do, if you have the right executable and know how to do it.

The benefit comes from it lets you focus on the problem itself, rather than deal with all the color and shape. Simplicity and right to the point.

But sometimes it could go rough, you got to tell it every detail while the same could simply be achieved by a mouse click in the graphic window.
