I am using Vegas 7 on my first V7 project, and let me say, the colors that show as event edges align with the edges of another event, even if on another track are really, really nice!
That essentially is what I have been doing for years, but with markers. Exact same same thing, but now I don't need the markers!
Good eh? - Just finished a piece with 9 tracks. As usual I'm all OVER the place! Sketches of ideas here, samples of stills and audio there, redundant prior ideas above, good stuff below .. somewhere . .. and so on - you get the picture?
Well, these Snap-To-Bars are a total Godsend.
I can now realign and replace using markers and have a "BANG-on" colour bar to confirm my position.
