Voucher exchange options

Perhaps this had already been suggested. If so, apologies.

Currently vouchers can only be exchanged for gems, food, certain granny items, etc.

Why not add a few more different things to exchange? Pearls? In particular, how about Pet food? 

As long as you didn’t complete it, you can go for landscapes plus gems. I did complete both of them.

You can use vouchers for bread, raid and turn the gold into items, which can be converted to pearls. 

Remember that keenflare not for nothing offers you to buy uber chests plus pal chests for gems, it’s one of their sources of cash. So I don’t see this happening.
