Making context sensitive help function truely context sensitive

There seems to be no obvious way to filter context sensitive help (invoked with F1). I have several different version of Qt installed (both from the 4x and 5x branch) and would like to see the help page related to the Qt version in the currently selected kit. Instead I am always presented with the help page related to one of the installed Qt version (apparently the first in which the key word is found). If such a truely context sensitive help is not possible, it should at least be possible to filter the context sensitive help manually, in a way similar to the method used in the help tab.

Furthermore, the help pages do not indicate the Qt version to which they relate. This is especially annoying, given the just mentioned problem, that the presented page does not respect the currently selected kit.

I would suggest to take the selected kit into account and to clearly indicate on the help page the version of Qt to which it relates.
