### 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)"
{
    SendCoinsEntry *entry = 0;
    
    if(ui->entries->count() == 1)
    {
        SendCoinsEntry *first = qobject_cast<SendCoinsEntry*>(ui->entries->itemAt(0)->widget());
        if(first->isClear())
        {
            entry = first;
        }
    }
    if(!entry)
    {
        entry = addEntry();
    }
    entry->setAddress(address);
}
