### Howto replace a stuck transaction with another with higher fee ?

bitcoind 0.15.0

The marking option "Request Replace-By-Fee" in the sending transaction GUI page should have a better understandable text.

The sender does not "request" anything when creating the transaction. This is just a tag for a later possibility, as I understand as a rather normal user.

I would suggest something like

"Let me increase the fee of this transaction later, if it should not get confirmed in expected time ('Replace-By-Fee' feature)"
if (rcp.fSubtractFeeFromAmount)
                CoinControlDialog::fSubtractFeeFromAmount = true;
        }
    }
    if (CoinControlDialog::coinControl->HasSelected())
    {
        
        CoinControlDialog::updateLabels(model, this);
        
        ui->labelCoinControlAutomaticallySelected->hide();
        ui->widgetCoinControl->show();
    }
    else
    {
        
        ui->labelCoinControlAutomaticallySelected->show();
        ui->widgetCoinControl->hide();
        ui->labelCoinControlInsuffFunds->hide();
    }
}
SendConfirmationDialog::SendConfirmationDialog(const QString &title, const QString &text, int _secDelay,
    QWidget *parent) :
    QMessageBox(QMessageBox::Question, title, text, QMessageBox::Yes | QMessageBox::Cancel, parent), secDelay(_secDelay)
{
    setDefaultButton(QMessageBox::Cancel);
    yesButton = button(QMessageBox::Yes);
    updateYesButton();
    connect(&countDownTimer, SIGNAL(timeout()), this, SLOT(countDown()));
}
int SendConfirmationDialog::exec()
