No, it's not more sexy but I just opened X3 to check something out and I noticed something right away when looking at the FX bins - eye strain. That cyan text against the black background. It was so hard to read. Now with the black text on the light gray background, it is better. It could use some more contrast but it is less work on my eyes.
I usually have the FX bin hidden on the Track View because I do all of my FX work on the Mixer view which floats on separate monitors but the FX bin in the TV is a thing of beauty. The only niggle I see is that there is some header text across the top which displays the number of plugins in the bin. I suppose that's supposed to help when you have the height of a track too short for all of the plugs to show up. Unfortunately, on my screen, when the plugins are hidden, a scroll bar appears and a scroll up arrow appears and now the header text is truncated and it no longer shows the number of plugins in the bin. Surprised that nobody caught that one though, it could be because of the resolution I'm using on my wall mount TV monitor. I'll check that out.
Another thumbs up for improvements to the FX bins.
EDIT: I checked the resolution and it seems that the headers get shortened on my other monitors as well. Maybe a different font size is needed?
