Regarding the OP, I for one like X3c quite a lot, but it is not without numerous bugs that are well documented and repeatable by numerous users (64 bit engine issues, take lanes in wrong order, snap to clip not working for some tracks). There are also some odd and workflow-slowing quirks, such as the fact that clicking DIM *then* auditioning takes works fundamentally differently than clicking DIM *while* auditioning takes. Took me a while to figure that one out. So, I can absolutely see why someone would not like using X3, or would hope/expect significant improvements.
Saxon1066A clip still will not paste into a selected take lane: it goes wherever it wants, sometimes erasing the clip it lands on. The new comping system is not as easy to me as just slicing bits of clips in the old layers system. Layers were better, more streamlined to work with. There are no advantages with take lanes. Since the way the tracks look and function during tracking and editing is the most important aspect to me of any DAW, X2 and X3 went in the wrong direction. I bought X3, used it, and I am on the verge of going back to 8.5 . . . again. Whoever thought takes lanes were a good idea never did many takes of multiple audio tracks.
Saxon, are you on X3c? One of the biggest improvements from X3b to X3c is how it handles multi-miced tracks. I could not use layers at all for drum tracking in X2b, but find X3c much better. I also find the issue of clips jumping around randomly when dragging to be *almost* gone in X3c, although there are still a few times I have run into it if I have many takes. I agree it does take up a lot of real estate. It would be great to have something like a "rebuild takes" function to consolidate unoverlapping takes like we used to have in 8.5, as well as more flexibility to resize takes.
As an aside, I second the notion that the Hide/show takes button should be available on a collapsed track.
