3D widget transparency, possible?

Just wondering if is it possible to adjust the 3D widget transparency values; you know the grab / rotate / move handles.

Tried to search inside User Preferences but found nothing.

Thanks!

no it isn’t , would be nice to have to on alpha .5 and when mouse over a handle it goes to alpha 1.0 etc

That was exactly my intention: at the moment I keep the widget disabled because it is too obstrusive, it hides too much the geometry behind it.

Let’s hope a developer can have a look at this little issue…
