+  - New "Gray" theme based on a 18.42% luminance middle-gray background, which
+    should be a good neutral environment for color work.
+  - The foreground/background editor in the toolbox will now take into account
+    the toolbox icon size and resize itself accordingly (live, as you change
+    theme). This allows to have really narrow toolbox when you use small icons.
+  - Theme-override icon size selection in Preferences > Themes: this allows to
+    override theme-set icon sizes, with a global concept of small, medium, large
+    and huge. The following widgets are so far modified: toolbox icons, fg/bg
+    editor in toolbox, fg/bg editor in Colors dockable, dockables tab icons,
+    bottom buttons (in the button box) of dockables, header eye and lock icons
+    above item trees, and eye and lock icon switches in item tree cells.
