Cuz of low Network fee on BTC withdraw my transaction is still unconfirmed after 3.3 hours, please make manual Network fee setting so we could pay more and get faster withdrawal
Personally I would be happy if a slider or even easier a multiplicator could be chosen on the withdrawal screen in the advanced view. This implementation would keep the simpleness for regular users in the regular view but also give advanced users the tools they need for advanced trading. A multiplicator would be a very easy to implement feature - just take the calculated standard fee and multiply it with whatever the user chose in the multiplier field.
Btw: This is not for BTC only but for every currency
