Not to get picky, but am I the only one that thinks the timeline becomes quite useless if you have to resort to work-arounds to address the inability to have an offset?
Generally speaking I avoid issues like this, but this one is just so incredibly brain-dead that it is annoying. Yes, I use the work-arounds, in fact my "standard" work flow includes two dead measures, and I always subtract two from whatever number appears on the timeline and/or clock, but dang, that's just silly!
Bit is right, I would expect that the numbers go far beyond simple labels, and changing this now would require changes all the way down to the audio engine level, and I'm sure that won't be fun. BUT, if they had addressed this back in the days of CWPA9, which is my earliest recollection of hearing about it, well, they'd be done!
