You can customize it in anyway you want, but in last update we did some major upgrade, which we explained here https://wordpress.org/support/topic/download-manager-is-moving-to-custom-post-type?replies=12

You just have to migrate data from Downloads >> Settings >> Migrate . The migration is require as with v2.7 wpdm moved to custom post type for better performance and security. you still can get back to v2.6.96 from here https://wordpress.org/plugins/download-manager/developers/

But if you want to stay with v2.7 ( which actually will be really best decision ), please let me know what you want to change, so that I can tell you specially about the required changes.
