The idea behind Equation Editing Application is very nice. It tries to use the precious screen space on the TI-83+ more effectively. It does this by emulating the 68K calculator user interface with the small font. This means that you have a one line editor on the bottom of the screen and have input/answer pairs in the top of the screen.
However, this appplication has a few things which make it not very attractive to use daily for me, but would make "EEA" better if the following were improved:
-It only supports OS 1.13, which is quite old and doesn't work very well with TI-Connect.
-It removes the [2nd]+Entry functionality. That would not have been such a great loss if the select answer functionality that I know the TI-92 calc has would have been replicated as well.
-The entered expressions can't be read if they are too large to fit on the same line as the answer.
