I'd like to have same kind of coloring in use for samples as we have for Beat and Bassline track items. It would make working with large data sets a lot easier. I like to work with samples and I often freeze short synth clips and then re-arrange them as samples.

Another working issue is human ear vs. normal metering. It's much easier to make tracks equally loud (i.e. gain staging in beginning of the mix) if you have "better" metering, something like LU or K-metering. VU is only energy amount, but for example, if you have sub-bass and high bell, equal VU sounds very different.
