My opinion would be:
1) Its a Hash for the keywords, I doubt it makes a measurable diff to have \
there some more or some less ones. 2) I would kill Qt4 and only keep Qt5, \
Qt4 is more or less dead for "new" things 3) Qt is one of the only toolkits \
around for C++, I think it makes sense to have per default highlighting for \
it.
