### 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)"
amount.append("</b>");
        
        QString address = "<span style='font-family: monospace;'>" + rcp.address;
        address.append("</span>");
        QString recipientElement;
        if (!rcp.paymentRequest.IsInitialized()) 
        {
            if(rcp.label.length() > 0) 
            {
                recipientElement = tr("%1 to %2").arg(amount, GUIUtil::HtmlEscape(rcp.label));
                recipientElement.append(QString(" (%1)").arg(address));
            }
            else 
            {
                recipientElement = tr("%1 to %2").arg(amount, address);
            }
        }
        else if(!rcp.authenticatedMerchant.isEmpty()) 
        {
            recipientElement = tr("%1 to %2").arg(amount, GUIUtil::HtmlEscape(rcp.authenticatedMerchant));
        }
        else 
        {
            recipientElement = tr("%1 to %2").arg(amount, address);
        }
        formatted.append(recipientElement);
    }
    QString questionString = tr("Are you sure you want to send?");
    questionString.append("<br /><br />%1");
    if(txFee > 0)
