When examining this theme I see that the min.png still is in this file and loaded as "min", but isn't used. Why?
After using Sunny Colors for the last few week, I went back to origianl Sunny again as a test today. I must say I perhaps liked the minimize effect of the orginal Sunny better. Just thinking out load here... a combination of them perhaps should be best? The transparency of the minimized icon from sunny-c and the looks of minimized buttons from sunny.
Ups, i see that i uploaded the old file I didn't noticed it because i used a dark panel background but i was thinking the same thing combining the two effects. If you invert the color of min.png, change the line 86 from <alpha_mask mask="mask" /> to <alpha_mask mask="min" /> and play with the minimized alpha you can see the effect in action
Hard to give any constructive feedback, it's almost flawless.
A feature request would be the use of the new size attribute. I use a customized version of Sunny without stacked icons for my netbook, because the icons look too small othervice. You could use stacked icons only for panels bigger than 25px, for example.
Are you going to update your older themes to support dockbarx 0.30 as well?
