+========================================
+New Content Element Wizard customization
+========================================
+
+Per default, all Mask Content Elements are grouped in "Mask Elements". If you
+want to group your elements in different tabs, you can do this by overriding
+page TsConfig. Unfortunately, Mask doesn't provide a proper API for this, so
+it looks a little tricky to do. You can also use this example to simply change
+the label of the Mask group. See the comments in the code.
