Good Idea - VERY Bad Implementation - Full of Litte unnecessary BUGs

The app while sporting many very useful features, is full of small bugs that makes it impossible to use.

The advanced features of the software works very well but operating it is next to impossible.
Geogebra 5 will let you enter a formular and display its result as a graph. However, it will re-format your formula and when you try to edit it,
in the new syntax it will throw an error. Then you have to re-write your original formula all over again.

Copy Paste tab operations are not in concurrance with OS X Guidelines and leaves the user with headaches and pain.

The programmers, clearly know their stuff - math-wise. But they have put little effort into making the application operatable !

Even though the app is free, I would recommend you stay clear of it. At least until they make it work.
