"Hide Generated Files" seems to do nothing in Qt Creator

If memory serves, in the past, unchecking this option, when on the "Projects" view, would enable one to see the

ui_*.h

files in the project tree.  For completeness, I would expect the

moc_*.cpp

files to be there too.  Naturally, these would change as build goes from Debug to Release.  However, adding a

ui_*.h

to the project, when "Simplify Tree" is not checked,  causes it and its folder to show up in the directory for headers, but its display is not contingent on "hide generated files" being checked.  This option is not present in File System view; but the "Show Hidden Files" doesn't affect their display there, either.  If I choose "Simplify Tree" in the Project View, the option also has no effect there, either.

If it is indeed working as designed, then I do not see what it is supposed to do, and the documentation could use updating; as it doesn't explain what else this option is for.  I would hope that this would indeed show me generated files which pertain to my current build type, which would naturally include moc_ files too.   It seems as if this feature has been broken without notice; but I, for one, like having quick access to these, for debugging, coding similar functionality, and widget navigation purposes - so I'd hate for this feature to vanish, when it is noticed that this option has no effect.
