Ok, I've read through the full thread before posting. Most of my major ones (esp. erratic automation -- that borders on achilles heel right there, for me at least) have been mentioned. To which I'd add non-show-stopping, but annoying as hell cumulative time vampires:
-- please let the display options for take lanes be the same as for normal tracks, i.e. we can minimize the height of all, then select just one, and adjust only its height. At present, adjusting the height of one adjusts the height of all.
I sometimes have 40+ takes (including some punch ins) so if I want to see one rather tall, they all go rather tall, even if only one is selected.
Also, it seems no matter which take lane I adjust -- let's say it's #20 out of 40 -- while I adjust the height, my whole display kinda goes into topsy turvy vertigo mode -- by the end of it I'm hearing the outro to Strawberry Fields Forever and I've been scrolled up to and dumped on the curb at Take #1, forcing me scroll down past 19 unintentionally high take lanes to get to #20. As I spend so much of my time comping, this is a major annoyance .
-- not huge, but again, at present, requires just that many more needless mouse moves to deal with -- in the browser, please have Recently Visited Places option just like in Windows Explorer. When I'm working on several different projects, I spend a lot of time going up the Sonar browser's tree to my root drive, then back down to the appropriate new sub-folder.
