This is a hack to allow the current menu and sub menu selection to be high-lighted.
It could also form the base for a breadcrumb block.
I hope this is the right forum.
The idea is to add a .current var to the $blocks array that is used by system_block_mainmenu.html.
Smarty logic can then be used to make the current selection look different.
A bread crumb block could loop through the $blocks the way system_block_mainmenu.html does and use only the .current links to make a bread crumb trail.
limitations:
If you have a module as your default page, the home link will not be high lighted.
3 files are changed:
Changes required to modules/system/blocks/system_blocks.php
Changes required to system_block_mainmenu.html
Changes optional to /xoops.css to indicate the current menu choice.

is changed. Here it is.)
