Ye, I'm currently looking at that. There seems to be some interest in
the project helping enhance labyrinth.

The obvious ones are the bounding box colour and the text selection
colour. However, there's also the primary thought and selected thought
default colours and the default background colour (white-on-black themes
for example). There are various other things like the default font and
I'm sure a few other things I haven't thought of.

He-he. Ye. DocBook is fun. This depends on when we're in a position
to propose for GNOME. It's possible by then we might have finished
working on a new format, Mallard XML, which will be easier. However,
until then, DocBook it is :(

The reason it's arrows is because I was experimenting. If there are
scrollbars, there is an issue of their initial state. Do you have them
cover 100% of the width / height? If so, people might not understand
they can move further easily. The canvas is supposed to be expandable,
to appear as needed in any direction as needed. With scrollbars, I
always feel they are a hard limit - you can't scroll past the end of a
webpage or a document. I felt this didn't really fit the feel of the
expandable canvas of Labyrinth, whereas the buttons did.
