New Help-System of Qt 5.6 is not optimal
one of the great advantages of Qt is the very good help documentation, especially the integrated context-sensitive offline-help. With Qt 5.6 it got a worsening.
Zoom is no more possible, only the Title zooms! A pity.
On windows the help system uses a very dense font. Search for example for "fillChar" in QString. It looks ugly. The "fill" part is dense pixel mash. Horrible to read this special part and the dense font in general.
The old layout was very clear, professional and beauty!
Why change good old things ?
Please bring back the good old layout or repair the new system!
I also feel the new format is harder to read and not an improvement.
However since this is user forum, mentioned it here will have no effect.
You could however ask the developers
or if you feel its broken, maybe even a bug report
To add to @mrjj, it looks like partly a bug in QtCreator, not Qt itself. What version of QtCreator are you using ?
You should take a look at the bug report system to see if there's already something about that matter.
