Having used it in this mode I would say its ok, not sure it helps or hinders workflow
If you’re trying to automate volume on audio its probably most use. perhaps a vocal - but extra space is used on screen
Would be cool if the automation overlaid, with no additional tracks, perhaps with the automation lines having a certain ‘luminance’ i.e the colours where extra bright so the user could visually focus on automation, perhaps selecting one parameter as the preference eg volume by default in preferences
then
if user zooms in, say to see one track only on screen, then all automation shows, still overlaid, in different colours, but each parameter could occupy a ‘lane’ overlaid - users would have to read the manual but I think this behaviour is ‘intuitive’ enough , i.e zooming in = more detail
If you think about it, it makes sense, to me at least
