It’s not irrelevant, it’s the MOST important issue if you’re a PRO. (it’s called Cubase PRO!)
If you didn’t like the design of Cubase 6 that’s fine, if you like your software to sacrifice speed and useability for prettiness, that’s cool, but it’s design is much faster to use/mix on and that’s a proveable fact.
The clue is in the software title… PRO!, and simply put, the hover thing is not PRO, it’s childish and amatuer-ish design and slows down the process of mixing a track, try mixing a bunch of records in a day with very strick deadlines and you’ll soon know the importantance of SPEED and USABILITY.
