A quick way to expand all tracks to a predetermind vertical size, and then a quick way to shrink them all back down to minimized. This would make it easier to quickly find a certain piece of audio i'm looking for by looking at the wavelengths in a bigger view.
 
This might already exist, but if it does I'm not quite sure how to do it...

It's not exactly what you're asking for, but, if you select all (Ctrl+A) and then Shift+Drag one track's height up or down, they will all conform to the same height. 
 

Not bad! I'll try that when I'm back to work on this project later. Certainly seems like it would be better than nothing :-)

Absolutely!   To add to your original request it could be convenient to have a few preset heights available, but this process is fairly painless.  

I have posted exactly the same request:
