Great Extension. I think it lacks some things :
1-shadow for text to avoid that become unreadable on white background
to enhance shadow my css solution
.Dashboard {
text-shadow: 2px 2px 4px rgba(0,0,0,0.8);
}
2-Excluding tag for custom search : these tags don't select the images that I don't want to show : for example something like *space and all image tagged with space isn't shown anymore...
3-Example and pattern for css.
4-slow living animation for image in css
@keyframes AA{
0% {transform-origin: 0% 0% 0;transform: scale(1.0);}
100% {transform-origin: 30% 60% 0%;transform: scale(1.2)}
}
.image {
animation: AA 65s linear 1s infinite alternate;
}
