Once you really start using Doit.im, you can end up with a very long task list in "Next".

A nice feature would be to provide an interface for filtering the task list (this could equally apply for Inbox, Tomorrow etc of course).

The key thing is the filters must be AND filters, which can be checked off such as:
Contexts:
Home: X School: Work: X Errands:
This would only show Home and Work context tasks.

These filters should also include options for "Priority" and any "Tags" you have defined.
