Is there a dialer app that allows multi-tasking?

[FuzzyB]

The stock dialer on my SG3 does not allow multi tasking...when I'm on a call there are many times I need to reference something in the device. Is there a good app that I can get that allows this to happen??

Why does the stock app not allow it? Or am i missing sumpn?
