If e.g. Qt 5.1.0, Qt 5.1.1 and Qt 5.1.0 is registered in Qt Creator, the Contents pane of Qt Creator help module will show three different top level nodes called "Qt Core". Even when clicking on them, one can only find out which patch level the documentation belongs to by right-clicking -> Copy full path to Clipboard.

I see two ways to fix this:

• Putting major/minor/patch level numbers in every page name:

"Qt Core 5.0.1"
"Qt Core 5.1.0"
"Qt Core 5.1.1"

• Only showing the latest version of a component, e.g. ignoring 5.1.0, 5.0.2 documentation for Qt Core if there's a 5.1.1

"Qt Core" (from 5.1.1)

Or, as a mix, only showing the latest patch level version for a minor number, but qualify major/minor numbers

"Qt Core 5.0"
"Qt Core 5.1" (from 5.1.1)
