I think a preference to use the sending address for change by default would be useful.

That's one of the options when you use this feature in "Expert" usermode.  You can select the specific address you want to send to, or you can select "Send change to first sending address".  There's also a button that says "Remember this for future transactions with this wallet."  Combine those two, and sending money will never generate new addresses.

It is incorrect to say you're compromising your privacy by reusing addresses. As you mentioned, there is a huge amount of linkage between your addresses. It has been shown that even if you use change addresses, you can still be easily tracked: http://anonymity-in-bitcoin.blogspot.com/2011/07/bitcoin-is-not-anonymous.html . However, transparently using change addresses makes bitcoins incredibly more difficult to back up correctly, since every time you pay, you have to back up new addresses. This is important, so It would be great if you could change your answer to reflect that.

If you are using Armory, the address chain is deterministic.  This means that you backup your wallet one time, and all addresses you ever use will be protected by that backup, even if you use millions of addresses.  This is why Armory discourages address reuse *when using Armory*... because you can use a new address everytime *without* complicating your backups.

Can I specify one of my existing "receive" address as a "change" address when I create a transaction when using the Bitcoin Armory client?
