How can I see tasks filtered by category?

rainmountain - Another possible work-around is to use Shared Lists instead of categories to contain all the tasks that are related. For example, I have a personal email and a work email. I also have separate computers for work and personal but want to be able to add or view the work tasks and the personal tasks from either computer. I do this by creating a shared list for work tasks and another for personal tasks. The Shared Lists are shared between my work Userid and my personal Userid.  This allows all my work and personal tasks to be visible across all my devices, including mobile. If you have a manageable number of categories, you could create a Shared List for each category. The shared list would only hold the tasks for that category. So, for example, if you wanted a category for Project X tasks, create a Shared List called Project X Tasks and use it for all the tasks for Project X. Do the same for Project Y, Project Z, etc. There's a bit of setup time to create the Shared List, but otherwise it seems to work.
