Would love to see Value Lists be a little more robust.
Specifically I'd like to be able to create a value list with Values + Descriptions without using a field/table source. This way I can setup a value list with some more context provided for the user but with a simple value selected instead of having to parse with a calc or setup a Value List table for simple VLs. This would be similar behavior to the Display Values from Second Field.
Another nice feature would be the ability to sort the VL for custom values. That way when adding values you don't have to manually sort (though that would remain an option).
