Difficult to find feature to change Qt Version

Steps to reproduce:

1. Add 1 version of Qt to VS Addin using "Qt VS Tools/Qt Options"
2. Create new Qt Console Application
3. Close solution
4. Delete the version of Qt from VS Addin using "Qt VS Tools/Qt Options"
5. Add a different version of Qt VS Addin using "Qt VS Tools/Qt Options"
6. Open solution
7. Build solution
   • Observe "Qt Visual Studio Tools" dialog that recommends to: "use the 'change Qt version' feature and choose a valid Qt version for this platform."
8. Right-click the project and choose "Qt Project Settings"
   • Observe there is no decoration that indicates that the Version field can be edited

I recommend changing the wording to read "Please use the \"Qt Project Settings\" editor to change the \"Version\" to a valid Qt version for this platform. Also, always display the droparrow on the combobox as a hint that it is an editable field.

I've wasted cumulatively about 1 hour trying to find the 'change Qt version' feature; the first time 6 months ago when I first tried to get the VS Addin to work with VS2013, and again with the beta version. This second time, I was about to google for it, then I remembered that I had googled for it 6 months before and that the option was hidden in plain site... somewhere.
