I don't believe that they can change paying for cancel order because bitshares work like that and they are on top of bitshares. They miss mobile app and liquidity. Many coins have low volume and big spread between buy and sell. For me UI is not bad and they are improving every month. You can even reach founder of OpenLedge, Ronny Boesing on Telegram and ask him what you want, he will answer. Overall, project miss some things but it has bright future. There is high chance that they will transfer platform to EOS in future and there is no fee on EOS so then canceling orders will be free :-)
