if there a way to add
for example when playing back audio,
a way to rank the audio or
preferably a fluid value
maybe via mouse-position/height hovering
or via keyboard +/-
and possibly later to use it for audio-filters
e.g. have parameters change over time
or use it for audio volume envelope (if it could also do linear,or smoothed, not just logarithmic decays)
or generalize volume envelope for any metadata or usage (thus making them convertible and interchangeable)
also possibility to move the meta-track relative to the audio-track ,
to compensate for human-factor-delays
maybe visualize it not only as waveform but maybe conditional formatting intensity bar…(gray-scale, color-tones)
and have possibility several of those tracks with different color maps…
