Seesmic Desktop default account for posting updates

By default, Seesmic Desktop sets "Share As" to the first account as listed in alphabetical order. This has caused problems a couple of times when I posted items to the wrong identity as I expect it to be set to the one I last used when closing the application.

In a perfect world, I'd like to be able to indicate in the Settings which account I want to post-to by default so when I load the application I wouldn't have to change "Share As" to my primary Twitter account.

Thanks!
