The widget controller has 2 overflow methods, Arrow and Popup. Both have issues that make them unusable. When using the arrow method, the arrow is tiny and disappears after one click. If you have several widgets that overflow, it takes more than one click of the arrow to get to the end. With the arrow disappearing after one click, the user will never know to click the same spot where the arrow used to be for more widgets. The popup option is also bad because you can't read the label. It says "More w...". Once the popup is open you can't see the labels due to the non-configurable white background.
The fixes would be to add the ability to configure the overflow methods for text color, background color, labels and icons. Also, fix the disappearing arrow problem. The arrow should not disappear after one click. If it has to disappear, it should only do so when the farthest end of the widgets in the controller has been reached.
