### 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)"
{
    clear();
}
void SendCoinsDialog::accept()
{
    clear();
}
SendCoinsEntry *SendCoinsDialog::addEntry()
{
    SendCoinsEntry *entry = new SendCoinsEntry(platformStyle, this);
    entry->setModel(model);
    ui->entries->addWidget(entry);
    connect(entry, SIGNAL(removeEntry(SendCoinsEntry*)), this, SLOT(removeEntry(SendCoinsEntry*)));
    connect(entry, SIGNAL(useAvailableBalance(SendCoinsEntry*)), this, SLOT(useAvailableBalance(SendCoinsEntry*)));
    connect(entry, SIGNAL(payAmountChanged()), this, SLOT(coinControlUpdateLabels()));
    connect(entry, SIGNAL(subtractFeeFromAmountChanged()), this, SLOT(coinControlUpdateLabels()));
    
    entry->clear();
    entry->setFocus();
    ui->scrollAreaWidgetContents->resize(ui->scrollAreaWidgetContents->sizeHint());
    qApp->processEvents();
    QScrollBar* bar = ui->scrollArea->verticalScrollBar();
    if(bar)
        bar->setSliderPosition(bar->maximum());
    updateTabsAndLabels();
    return entry;
}
void SendCoinsDialog::updateTabsAndLabels()
