They need to have cards going both directions so one side isn't bulging out.  I filled every card slot (my favourite feature) and when closed, one side was giant compared to the other.  By the time I put a bit of bills in, there was no room for my small phone without seriously distorting the wallet and risking breaking it on the loosest snap.  How about a longer closing snap strap to accommodate the fully packed wallet?  Might be a quick fix to an otherwise great product.  My black grain leather smells like leather, feels great and if I can have the snap strap lengthened, it just might be exactly what I needed.
