Ok.

I have only looked at the part which interest me at the moment, the 
saving of the windows layout (the GdlDockLayout object). From what I 
have seen, the architecture seems good and I don't see much things to 
remove. But I have looked only at a small part and indeed the 
GdlDockPlaceholder object seems unused, I suppose it can be removed. Do 
you have in mind other things those could be removed?

I'm agree that currently GDL is quite unusable due to the lack of 
documentation. But I think I have in mind something less formal, rather 
read a piece of code, try to understand it then modify it and document 
the result. I prefer to play with a part of the code and understand it 
piece by piece.

I plan to change the GdlDockLayout item to keep track of hidden dock 
items. So when saving a layout, instead of clearing the old one, I would 
rather mark all windows as hidden and try to merge it with the current 
layout.

I have seen that currently, it uses libxml2 which is a good and stable 
library but I think it's not really necessary for such a simple usage. 
So perhaps it could be better to use the xml parser integrated inside 
GLib allowing to remove this dependency.


> What does everyone think about this?

I have planned to improve the saving of the layout, gain some knowledge 
about GDL and then look at the bugs as I don't think there are really 
critical bugs.
