### 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)"
{
    QPair<QString, CClientUIInterface::MessageBoxFlags> msgParams;
    
    msgParams.second = CClientUIInterface::MSG_WARNING;
    
    
    
    switch(sendCoinsReturn.status)
    {
    case WalletModel::InvalidAddress:
        msgParams.first = tr("The recipient address is not valid. Please recheck.");
        break;
    case WalletModel::InvalidAmount:
        msgParams.first = tr("The amount to pay must be larger than 0.");
        break;
    case WalletModel::AmountExceedsBalance:
        msgParams.first = tr("The amount exceeds your balance.");
        break;
    case WalletModel::AmountWithFeeExceedsBalance:
        msgParams.first = tr("The total exceeds your balance when the %1 transaction fee is included.").arg(msgArg);
        break;
    case WalletModel::DuplicateAddress:
        msgParams.first = tr("Duplicate address found: addresses should only be used once each.");
        break;
    case WalletModel::TransactionCreationFailed:
        msgParams.first = tr("Transaction creation failed!");
        msgParams.second = CClientUIInterface::MSG_ERROR;
        break;
    case WalletModel::TransactionCommitFailed:
        msgParams.first = tr("The transaction was rejected with the following reason: %1").arg(sendCoinsReturn.reasonCommitFailed);
