How do I set the transaction fee in Multibit? I can't see any options in View > Preferences nor on the Send tab!

I can't find any results in a DDG search!
The developers of Multibit have explicitly disabled such a feature to change the transaction fee, citing concerns that having little or very low transaction fees would result in the transaction taking too long to process (which is going to be unbearable for the average user only interested in sending and receiving money quickly).
From the GitHub issue originally submitted, the developer explains:

The reason for this is that whilst in theory it is possible to send BTC with zero fee in practice it is not. For the &quot;regular user&quot; (i.e. someone who just wants to use bitcoin and does not really know the details) their user experience is quite poor with zero fee tx. We have probably both experienced this with Instawallet (zero fees added) where you sometimes have to wait until the next morning before the miners decide to add your tx to a block.
It would create too much frustration to users (and too many support calls for me) to have zero fees.

Note: tx means a transaction.
