The 'new look' is generally much harder to use than v1.3
I've tried both the 'light' and 'dark' styles in v2.0 (I run Windows XP) and neither of them work for me, or more specifically, for my eyesight. I suspect that many other users will have the same problems.
'Dark' makes everything nearly invisible; 'light' makes the blue highlight colour nearly invisible. There is no setting I can choose which makes the program anything like as usable as v1.3. I also dislike the rounded corners on all the controls: my pet hate! And the 'crossfade' animation when clicking different tabs in dialogs (such as Preferences) makes me nauseous, I'm afraid (I had to switch off ALL Windows visual effects for the same reason): it would be much better if that could be switched OFF.
PLEASE can I have an option to make v2.0 look like v1.3? Or at least, to look like a standard XP/NT Windows program? I'm worried that I may have to give up MuseScore completely if this can't be addressed, and that would be a tragedy, as it is far and away my favourite engraving program. And as I said at the beginning, I think many other MuseScore users will have the same problems when they finally see v2.0.
Please don't ruin your GUI just because you have some misguided idea that it has to 'look new!' The v1.3 GUI 'look and feel' is just fine!
