Playing around with the prompt lists made me wonder something. How do lists of different lengths interact with each other? Some lists are very long, while others are shorter. My suspicion is that long lists may wind up putting more prompts into a card where several lists are merged.

Might there be a way to toggle between "merge all lists and select randomly" (which will weight toward longer lists) or "take similar amounts from each list" (which will balance lists)? It would probably have to be restricted by numbers; frex, you could do 2 lists with 12 prompts from each, or 4 lists with 6, etc.
