macsmet's screendesign is damn close to what I feel it needs to have. The current official one looks way too clustered and, let me be very open without taking any offence, halfhearted. Neccessary changes would be:
- less graphical cluster including less different backgrounds (usability and branding)
- more comprehensible and bigger icons (usability)
- clear position of the WB icon on top left (branding)
All this comes with macsmet's contribution. I only would like to have the log-out button changed. I also like it most because it comes with less glassy look - don't you know, fellows, that the glassy look is about to disappear again and clean structures revive?
Eki's contrib is quite alright, but not consequently developed. And tiesy's screendesign still looks too clustered (too many backgrounds). But I like your set of icons for the tasks overview and the Add-ons overview, they look very comprehensible to me. The icons on the right top are too dark and somewhat unclear, compared to their counterparts in macsemt's design.
By the way, it not just a matter of taste. It's a matter of comprehensiveness, usability and branding.
