dunno if it came up, but I also think that a group to clip which groups several clips which are in the same track would be cool, in addition to a 'follow clip in another track' (yes can be made with m4l, I know).
+ on the group track in session view would be great to have the number of clips contained in the group and not just one colored box:
similarly to the arrangement view but vertical (standing next to each other).
+ possibility of switching groups and all sub tracks on off without freezing, and effectively improve CPU time.
a button on the right corner of the group track would do it.
m4l : switch undo mode on/off for live.object.
better timing performance in regards to synced m4l patches.
Stability and better performance. on a 2GHz Core 2 Intel 2 GB RAM machine not being able to run Live 8 at less than 512 samples/buffer without encountering some problems, and with very few tracks playing, is uncomfortable, but I am still in love of course...
