I keep all my routine tasks in a separate folder.

I then have multiple "today" context perspectives:

Today-R: available and due/flagged with focus that excludes routine tasks.
Today+R: available and due/flagged with focus that includes routine tasks.
Routine: available tasks with focus on just routine tasks.

I actually have 2 versions of the above, one for work and one for home and these 6 perspectives are pretty much all I use.
