Breaks away from the thesis are good, or so I used to tell myself ;-)

Yes please, editing .hpp and .cpp at the same time will be a great step

Whilst looking at two places of the same document is also a use-case of
split windows, if this restriction allows the initial implementation of a
proper split window system more easily then lets start with it. All I
would say is try not to make it too hard to expand later.

So long as manual sizing is still available, fine, Geany is not smart
enough to always know what width/height I need.

Its gotta happen at some point, so long as the changes are sensible and for
a good reason then its ok, but I would probably say that means make the
change after the next release, so there is no rush on trying to get a big
(well big relative to recent ones) API change tested and into the plugins.

Will look at it and try it as soon as I can, but some guy on IRC keeps
prompting for feedback :)

For me this is second only to multiple windows as an editing feature that
Geany needs, and I expect it is an important step towards multiple windows.
