Unexpected behaviour:

1. My main menu has no background ( the bg it has i assume is a built in 
default)
2. On switching from my 2nd menu back to the main menu i get a black 
screen with the prompt "boot:"  pressing enter clears this and displays my 
main menu as above (ie no custom bg just defaults)
3. If i edit the APPEND line in conf/x86-4.conf that returns me to my main 
menu to "APPEND gfx/default pxelinux.cfg/default" it works.

Other than the above seems to work fine (only been playing with it for 
15min so may be more to come.. hopefully not though)

May I suggest the following as poss solutions:
1. Where we declare we want to use vesamenu at the top of each cfg file we 
pass the "default" gfx cfg file we want to use there.. "DEFAULT 
vesamenu.c32 gfx/default"
2. We have a fixed file location like pxelinux, if there is a folder 
called gfx it will use the file there called default if present and then 
additional/other files are declared inline as they are at present
3. A constant is added to the top of each file #!cfg or #!gfx and 
depending which is present then the file is either menu items or gfx 
configuration

Appoligies if I seem blunt above but just wanted to list what I viewed as 
unexpected in a simple and direct way.
I truely am grateful that you have begun to implement this as it will save 
me (and alot of other people) lots of work for simple changes.
