### 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)"
{
    updateYesButton();
    countDownTimer.start(1000);
    return QMessageBox::exec();
}
void SendConfirmationDialog::countDown()
{
    secDelay--;
    updateYesButton();
    if(secDelay <= 0)
    {
        countDownTimer.stop();
    }
}
void SendConfirmationDialog::updateYesButton()
{
    if(secDelay > 0)
    {
        yesButton->setEnabled(false);
        yesButton->setText(tr("Yes") + " (" + QString::number(secDelay) + ")");
    }
    else
    {
        yesButton->setEnabled(true);
        yesButton->setText(tr("Yes"));
    }
}
