Editing Permission Levels Page

More for a personal note, going to the Permissions page takes a few clicks so why not just put /_layouts/role.aspx in place of pages/default.aspx of the home page URL.

http://serversite/_layouts/role.aspx - Gets you to the Permission editing page where you can edit permissions for each Permission Level i.e. add/remove delete permissions, add items permssions, and lots more.
