When i do tools-options i see a list of icons with text caption onthe left vertically, each of them opens a corresponding panel on the right.
There is no Qt Versions, only Qt4 or Version control.
Under Qt4, there is a table of options, table has columns "Name, qmake location,Debugging helper"
Table contains values
