- The "light" icon theme is now a little lighter, to increase contrast. - Toolbox icons are now small. - Buttons: - Buttons without labels which use icons as their only source of info regarding what the button does (e.g. the white-balance pipette button) use normal-sized icons. - Labeled buttons which use icons as an auxiliary source of information (e.g. Auto-Crop) now use small icons. Curve type icons are also small even though they have no labels. - Colored circles are smaller. - Curve type icons redesigned and small. - Hand icons (when panning the preview) redesigned to have a clear outline regardless of background color. - Magnifier icons redesigned to have a thinner magnifier frame and larger inner parts. - Perspective, distortion and crop icons redesigned. - Some small icons were missing the `-small` suffix, now renamed.
