### 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)"
{
    GUIUtil::setClipboard(ui->labelCoinControlQuantity->text());
}
void SendCoinsDialog::coinControlClipboardAmount()
{
    GUIUtil::setClipboard(ui->labelCoinControlAmount->text().left(ui->labelCoinControlAmount->text().indexOf(" ")));
}
void SendCoinsDialog::coinControlClipboardFee()
{
    GUIUtil::setClipboard(ui->labelCoinControlFee->text().left(ui->labelCoinControlFee->text().indexOf(" ")).replace(ASYMP_UTF8, ""));
}
void SendCoinsDialog::coinControlClipboardAfterFee()
{
    GUIUtil::setClipboard(ui->labelCoinControlAfterFee->text().left(ui->labelCoinControlAfterFee->text().indexOf(" ")).replace(ASYMP_UTF8, ""));
}
void SendCoinsDialog::coinControlClipboardBytes()
{
    GUIUtil::setClipboard(ui->labelCoinControlBytes->text().replace(ASYMP_UTF8, ""));
}
void SendCoinsDialog::coinControlClipboardLowOutput()
{
    GUIUtil::setClipboard(ui->labelCoinControlLowOutput->text());
}
void SendCoinsDialog::coinControlClipboardChange()
