Played Wishing Well, then I couldn't figure out how to name Gladiator.
As the supply pile had Fortune on top.
Re: split piles
I couldn't find any option to look at more cards than the top one for split piles (right-click), Knights, etc.
With some you should definitely know (split piles, Knights), with some I think it's supposed to be secret (Ruins)?
Also for evenly split piles it might be useful to see how many of each there are remaining.
Something like 2/5 for 2 Settlers/5 Bustling Villages.
For Castles and Knights you can just do the total count.
