I have upgraded my ZEN wallet to version 1.1.5, which actually gives me better visual experience. Of course, I don't have more than 1000 ZENs to try sending such a huge amount of coins. Nevertheless, I think that if new version of ZENcash wallet can completely fix bugs related to limited amount of coins to send on ZEN network, it will be great news for whales (who usually own lots of coins and need to move their coins as fast as possible.)
Thanks for all upgrades, MedaR.
