A lot of work went into re-designing the part appearance and display behaviors, consolidating all the different display/draw modes which where added over the years into the program. There was a lot of interdependency of all the different combination and modes which culminated in rather awkward code to maintain - or to extend. Nearly impossible. With Nuendo 5 the first batch of part appearance changes was introduced, with Cubase 6 we got it all together. Tidy, and modern looking, and with user controllable settings. It takes a bit of time to get used to it but compare a complex project in Cubase 5.5 with Cubase 6: It has a much calmer look and once you have seen it in action you will notice that there is purpose behind all this. As a tip: Ever wondered by "Use Background Modulation" and using the Range Tool never got nicely together? In Cubase 6 it all works and looks as it should and removes much of the "clutter".
To answer the question about Transparent Events: The term itself (when viewed from Cubase 5.5 point of view) is a bit misleading. But we know why people have been using it, there are usecases where you need to see the grid underneath e.g. a peak of a waveform. Unfortunately we could not yet re-implement it back in time - but on the other hand we are now in the best position of having a fresh, modern looking appearance and adding it back without doing nasty things to achieve it. It is just not ready yet, sorry.
