Still needed on iOS apps. Thx.

oh, yes please! The ability to "select all" on iOS would be very helpful.

Yep. Some of my lists have 100+ items. Touching each one individually to select it is a major pain.

+2.
I use RTM as a shopping list, all items need to start completed. Because the default sort order for completed tasks is the completion date I need to select all items, uncomplete them, select them all again and complete them thus forcing an alphabetical sort order. I have to do this on my desktop because there is no facility to select all in the Android App. Please allow me select all or provide a sort order feature for completed tasks.

Must have! I waste minutes of my time every day on this.

Please please... I absolutely need this capability; currently I have to rely on the PC client to practice my daily ' Procrastination En Masse'... [a.k.a. Select + Postpone all]

Add a press and hold to select all items anyplace you select a single item. Or make a first item at the top of the list when selecting an item in Edit mode that says () All Tasks.

Actually, an easy fix would be to just add Select All as a menu option to the menu that appears after you press Edit and then select an item. No other interface changes needed. Just a single menu item added.
