A Tomorrow folder is very useful (in Do section). When it's impossible to do a task today is better move to Tomorrow than to Next. Next folder it isn't Today, it isn't tomorrow.. is too imprecise, and Scheduled isn't the best option for look the tasks for tomorrow quickly. The implementaton I think is easy because Tomorrow Folder contains the Sheduled tasks for tomorrow. It could be a option for Tomorrow floder: Visible or Not visible.
