navit.xml layout changes

[Mineque]

Things i would like to have in navit and i guess might be usefull for others 

1. Defining map background color tag in <layout> </layout> section not hardcoded like it is now 2. Removing all poi element from layout section to external file poi.config/default.poi Advantages? 
a) defining different config for different devices (Neo1973, N800, PDA etc.) 
b) creating new set's of poi's icon c) personal displaying order for users with having at the same time default not modified poi.config 
3. Removing and splitting whole <layout></layout> section to two different files. First describing colors (e.g. default.colorset) second describing layout and font size (e.g. default.layout) 
Advantages? 
a) defining different config (font size etc) for different devices (Neo1973, N800, PDA etc.) 
b) a way for creating new map's colorset
