Previously (when view creation was lazy) there was a delay
on first switch to
a document in creating the view anyway. However, this can
be made less
noticable (see below).

I'd like to see preloading of open documents to the left +
right of the
current document (if they're not already loaded), plus
possibly preloading of
the corresponding header/source file (if it is
"open" in kdevelop already).
This would eliminate most of the delay as is at the moment.
Cheers,
Hamish.
