The Pointer select menu only shows 50 items if there is no +*options, or its WQL is "{}". Looks like it's coming from WQL returning 50 cards at a time by default. Easy workaround: the menu gets 100 items with WQL of {"limit": "100"}
put 20,000 cards in a selectbox and you'll crash a browser. must be some default limit and some way to override.
default to showing all *options in *input menu+discussed in support tickets
