I like the eye dropper. Although, I think the icon should have been a pointer clicking on a circle or something. When I see an eye dropper, I think it has something to do with color. Like, maybe changing the color of the object or something. But whatever. I know what it does now and I’m sure everyone will just have to learn.
I’ve heard this anti-clutter discussion before and I totally agree. But, I really feel (and this is going to be hard to swallow I know) that part of the issue with Clutter in Blender is due to the double columns of data and buttons in the properties panel. A long time ago I read about a study that looked at different panel configurations and they found that it was more easy to remember where things where with a single columns of data. Something about only having to read the first few letters to identify the property but when there are two or more, your eye has to work harder to scan across each button/text bit, all while scrolling down the panel.
I have to agree too. For some reason, even though I know where most things are in Blender, I sometimes fail to see them when they are right in front of my face. Some day I would love to see a single column layout for the properties panel. If this proves to just be to much scrolling, we could introduce sub-tabs to organize more related properties into groups better.
