I've used Apple Mail for years but struggled so long with the folder structure. I would love for my multiple "Mailboxes" (folders) to go under the Inbox like such:

The reason being when I create new mailboxes they go to a completely separate heading under that e-mail address. So when my searches in Apple Mail are not comprehensive, as it'll often search the Inbox without searching the other Mailboxes. This is such a simple feature yet my web searches have proved fruitless. I've also contacted my ISP Host Gator but recommend that I ask Apple or search the internet. Any help would be much appreciated!
