Subject: Re: please, where has xconfig KConf option documentation gone with
 linux 4.8's Qt5 / Qt4 xconfig ?

 Aha, thanks! I never would have known this without being told -
 there is no visible indication that the symbol info pane exists
 at all until one tries to drag the lower right corner of the window
 notth-eastwards - is this meant to be somehow an intuitive thing to
 do these days to view more info ?

 I did manage to view the option documentation with nconfig  /
 using emacs to view the KConf files (preferable).

 Really, it would be nice if xconfig had some 'View' Menu & one could select
 View -> Option Documentation  or press <F1> over an option to view the
 documentation for it , and if the geometry of the different panes was
correct at
 startup .- the whole Option value pane initially appears on the far right hand
 side, about 10 pixels wide , until resized ; and there really is no sign of the
 documentation pane at all until lower right-hand corner dragged.

 Also, in the Help -> Introduction panel, it says :
   "Toggling Show Debug Info under the Options menu will show the
dependencies..."
 but there is no "Show Debug Info" option on the Options menu - sounds like
 it might be a useful feature - should I be seeing a "Show Debug Info" option ?
 why don't I see one ?  Maybe the Options menu might be a good place to put
 an "Expand Option Documentation Pane" option ?

Thanks anyway for the info.

Regards,
Jason
