Your master display will need to be in stereo, unless you never work in 
stereo.  2nd, actively converting 32 float into 8bit all the time would 
take even more processing power than just using the 32bit float 
masterbuss output.  Maths becomes involved.  Every time you change 
something if will have to use a custom audio engin, not written yet to 
sense the changes (with effects) and print it to the 8bit file, using 
the 32bit to 8bit converter.

I may be old fashioned, but it all seems a bit much, just to be able to 
see a waveform that may or may not be accurate.

If this is to be implemented, it needs to have minimal impact in the 
current engin.
