Reloading of the theme results in a screen flicker as the terminal window is 
shown before the theme reloads.

I cannot code in C nor do I profess to be anywhere close to scripting as you 
guys, but I think a better solution to fixing the submenu issue would be from 
source code.

Is it at all possible to simply load the menuentry items under the submenu 
command without having to reload the entire theme?  If it can be done, wouldn't 
it prevent the flicker seen as the theme reloads?
Problem is that it's possible to do something like:
submenu "xyz" {
And thus change the theme for submenu.
While at it, could you also please fix the keyboard lag that results when a gfx 
theme is used.  This is an issue with many users of gfx themes .

Thank you.

The only way a regular user can workaround this at the moment is to reload the 
theme after the submenu menuentry item is selected.

In Ubuntu's (about the only distro that uses the submenu command at this time) 
use of the submenu in 10_linux:

     if [ "$list" ]&&   ! $in_submenu; then

A regular user must patch 10_linux thus:

     if [ "$list" ]&&   ! $in_submenu; then
       echo "submenu \"Previous Linux versions\" --class submenu {"
           if [ "x$GRUB_THEME" != x ]&&   [ -f "$GRUB_THEME" ] \
               &&   is_path_readable_by_grub "$GRUB_THEME"; then
               prepare_grub_to_access_device `${grub_probe} --target=device 
               cat<<   EOF
set theme=(\$root)`make_system_path_relative_to_its_root $GRUB_THEME`
What a perfect example of overengineering just to compensate for missing
"export theme". I've fixed it in trunk
to reload the theme and have a themed submenu.

Will this be fixed in the 2.00 release?
