Pitch Bend?

is there any way you could add pitch bend either as a plug in, or as a feature in a future version? The only audio app that I’m aware of that did this on a mac was Snd sampler, but it is no longer made anymore (sadly). its such a pain to open MP3s with it, so I thought I’d ask if this could be added if its not already. thanks!

How about Sliding Time Scale / Pitch Shift? http://manual.audacityteam.org/o/man/sliding_time_scale_pitch_shift.html
