Can the OS X Mail dock count be made to show all (not just unread) count of inbox? A few other e-mail applications allow you to set their dock counter to the number of messages in the inbox, rather than just the number of unread messages. The idea being that until it's out of the inbox, it's still an active task that needs to be resolved.

So what I'm after is the ability to do this with Mail.app in OS X Mavericks. Currently there's only a drop-down preference for:

Dock unread count: Inbox only
                   All Mailboxes


Perhaps there's a plug-in or some other app that allows you to override the inbox count with the total count?

Unfortunately, searching on Google for anything to do with the inbox count just brings up hundreds of posts about how the count is wrong/not showing. Hard to find anything useful amongst countless pages about bugs.
DockStar solved the issue for me. It now has an update to support both Mavericks and Yosemite when it comes out. I only tested in on Mavericks though, works great.

The great thing for me was that I have exactly 4 inboxes, so I can add a badge for all of them.
