A player should have the option to show their development card(s) to the table instead of them being a forced mystery. This would be useful for a number of scenarios (for example, proving you don’t have largest army in hand). An argument could be made that in the real life game the rulebook doesn’t mention this as an option, but in colonist.io you can already reveal your hand using the blank trade feature anyway. Additionally, this could just be made an option for the host to choose from when making a lobby if everyone doesn’t want to play this way.
