I hoped Service Pack 1 would address the issue, but it didn't. Apparently, Corel doesn't regard this as a problem, but this IS A PROBLEM!
I don't understand, why do I have tons of "Layer 1" accumulated in my SINGLE-PAGE document? Why do I have to sort them and delete many EMPTY layers left from something God only knows what. Excuse my lack of serenity here, but I've just done another of such frustrating cleanups and I'm really annoyed.
Shortly, return the old layer system. Whatever good reason was behind this new system, it's something WE DON'T NEED!
