Breadcrumbs for multiple menus

Hello all, thanks for this great module.

I've installed the latest dev module specifically to get the functionality added from this issue thread:
http://drupal.org/node/430290

I was wondering if this patch could be expanded to add the ability to generate breadcrumbs based on multiple source menus?

Additionally I've noticed with the aforementioned patch the Menu Trails screen takes substantially longer to render for large sites with many menus, would it be possible to select mutliple menus with a combo box, instead of a pulldown menu, at the top of the module page and that would make only those menus available for creating paths and generating breadcrumbs?

I realize I'm asking a lot, I'm willing to help but I'm really a beginner in PHP development, so it will probably be some time before I'm able to get anything like a patch together to do this so I though I'd put it out there for the community.

Thanks for everything
