I like the improvements in the new GUI: It makes sense that related functions are organized logically in the same panels. The mixer that allows you to simultaneously see information for each track and to solo, mute, freeze, etc., is also a big plus. But there are two long-standing issues I really wish they would have addressed: the Mac version still makes you look at measures 1-64 or 65-128, but once you're on 65, there is no way you can see the chords you just entered in any measure before that. And there is still no way to transpose part of a song, so you can't even do something obvious like take the last chorus up half a step, without some awkward cut-and-paste workaround. If these two issues were fixed, it would help my work flow greatly. Maybe some day?
