Even though the Mix Console is much better than before, I still think that the issues mentioned here would definitely make its workflow even better. Steinberg needs to look back at the previous mixer and bring back the things it did well. Yes, the mixer in Cubase 6 did not display Inserts and Sends at the same time, but the information it did display was presented all at once and without clutter. That's the kind of functionality that needs to be present in the current mixer.
The other thing, and this is probably of higher priority in my view, is the hidden plugins issue. This needs fixing ASAP!! Even with the single click behavior back, one still needs to click twice every time the plugin goes underneath the mixer (which happens every time the mixer is not the focus; so it happens a LOT). Still a clicking fest.
