TaskSurfer gives you all of the tools you need to manage things the way you want. Stick things in folders, use contexts to decide where and when to work on stuff, or tag it with a location and let your Mac sort it out for you. Go crazy with tags and use the Tag Browser to keep it sane. Because TaskSurfer is written on top of core Mac OS X technologies, you'll be up and running right out of the box.
What's new in TaskSurfer
The sidebar now has an "All Tasks" item that shows all tasks, depending on the filters one has set.
The task count badge for folders and contexts is only shown if there are tasks for that folder or context.
