### 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)"
{
    
    
    pasteEntry(rv);
    return true;
}
void SendCoinsDialog::setBalance(const CAmount& balance, const CAmount& unconfirmedBalance, const CAmount& immatureBalance,
                                 const CAmount& watchBalance, const CAmount& watchUnconfirmedBalance, const CAmount& watchImmatureBalance)
{
    Q_UNUSED(unconfirmedBalance);
    Q_UNUSED(immatureBalance);
    Q_UNUSED(watchBalance);
    Q_UNUSED(watchUnconfirmedBalance);
    Q_UNUSED(watchImmatureBalance);
    if(model && model->getOptionsModel())
    {
        ui->labelBalance->setText(BitcoinUnits::formatWithUnit(model->getOptionsModel()->getDisplayUnit(), balance));
    }
}
void SendCoinsDialog::updateDisplayUnit()
{
    setBalance(model->getBalance(), 0, 0, 0, 0, 0);
    ui->customFee->setDisplayUnit(model->getOptionsModel()->getDisplayUnit());
    updateMinFeeLabel();
    updateSmartFeeLabel();
}
