The Lists page gathers all the ready-made lists Marvin can show you, plus the smart lists you made yourself. Open it from More > Lists.

Two tabs
Lists: built-in lists grouped into sections, like Everything, Planning, Projects, Inbox, Deadlines & Urgency, By Duration and Priority.
My Smart Lists: the smart lists you created. (Shows up when the Smart Lists feature is on.)
Which sections you see depends on the features you have on. For example, "By Size" only shows when T-Shirt Sizes is on.
Some examples of built-in lists: All open items, Recurring Items, Saved Items, Dusty items, This week, Overdue, Due soon, Next actions, Most Important Projects, Quick / Medium / Long.
Opening a list
Tap it. A back arrow at the top left takes you back to the Lists page.
Organizing the page
Reorder: press and hold a list, then drag it.
Hide a built-in list: swipe it to the left and tap the eye.
Rename or delete your own smart list: swipe it to the left. Deleting a smart list doesn't delete the tasks in it.
Groups: tap or hold a section heading to rename it, move it up or down, or delete it. Tap New group at the bottom to make one.
Choose which lists show here: at the bottom of the page.
