+// So why did I split uiCombobox into uiCombobox and uiEditableCombobox? Here's (90% of the; the other 10% is GTK+ events) answer:
+// When you type a value into a NSComboBox that just happens to be in the list, it will autoselect that item!
+// I can't seem to find a workaround.
+// Fortunately, there's other weird behaviors that made this split worth it.
+// And besides, selected items make little sense with editable comboboxes... you either separate or combine them with the text entry :V
+
 // NSComboBoxes have no intrinsic width; we'll use the default Interface Builder width for them.
 #define comboboxWidth 96
