Magento modification to free custom menu extension (exploded top menu's)

I require a small modification to a Magento Module called Custom Menu 2.8.0 found here: [login to view URL] The module will create exploded menu items for each category and place them in the header of the web page. The problem is that because I have so many categories, this makes the header incredibly large. If I re-sort my categories this will affect some import scripts and URL rewrites which is not an option. What I would like is the following: 1. That a solution be found to place all my categories within 1 drop down menu in an exploded menu. 2. A solution that if I want to add another top level menu in the future that it can be done easily 3. The ability to have a separate top level exploded menu for CMS pages I have attached an image of part of my existing header and a small explanation of what I am looking to achieve. This shouldn't be a difficult task for any experienced web developer and I am not looking for any decorative customization. I am simply looking for the above 3 requirements. This shouldn't take more than a few hours ( 1 - 3 hours). Please bid accordingly.
