I find it extremely fascinating that Live users are willing to sacrifice CPU and change audio buss routing all for the sake of visual & kinesthetic organization and workflow. Ableton? You guys listening? All of this effort just to fold tracks!
yeah well. i didnt really need this until lately, before that i usually didnt have alot of track. now i can easily end up with 50+ tracks and not beeing able to group them for easy management is just a workflow stopper. atleast this way i can have all my bus groups with fx groups per bus group (got that?) and be able to quickly show/hide them to quickly and conveniently find what im looking for. anyone whos worked with any type of track grouping options before knows how useful this is. its not a complete workaround but this way you can simply just fold all the tracks to its minimum one play button style width and put them all the way to the left/right, making a makeshift hide group by placing them out of the way with the scroll bar position heh, and then use the show/hide group of the midi tracks and work with the different groups there. then ofcourse if needed you can resize the tracks to go directly to the source audio incase you want to change it.
if you still dont get it, make a big project with alot of tracks and just simply try it. youll be amazed as to how it will help you work and organise things for a faster workflow. seriously. especially with working with multiple groups.
yes, it does sacrifice cpu, but dont wine on me for that, whine on ableton.
