Thank you @fengzhiyan @JapieAmerika
@RomanV We're working on GUI wallet now, there is no specific date for release yet as we've just started project. It took 2 years for Monero to have first official GUI wallet, so be patient

I understand. Even believe that the current wallet is quite a convenient. Just need to maintain interest at this stage. That's why I asked. It's not so much in the wallet. Miners need returns, etc..
Will watch the development. Thanks for answering.
