i also notice that my CPU load is very minimal when recording and wonder
if this is some headroom to capitalise on. many other DAW do this and
hobby editors offer this.

i think rendering a waveform during this time is not just eyecandy, or comfort 
(is anything actually happening?) but also a way to measure whether the 
signal is too low or too high in an updated graph. 
sure the db metres offer that but without a cumulative
update. i agree it's not *that* important..
