It works well. I used it for weeks in replacement of simplewallet and it fits my needs without bugs. I mainly focused or code architecture in order to keep it flexible and future-proof.
However, I keep it for devs only until more Monero Core features are implemented. (I will try to participate).
If you want, you can try the version I use in my Windows 8 (x64) tests here :

About the RPC-free wallet, compiling with it is a tedious task because required code is not part of official Monero repository. Thus, bitmonero-qt can still be used with simplewallet/RPC.

Nice work! I see that you are very interested in a special Core concept.
You have added some great features (I didn't try them all), including custom TX fees, and I see that a deeper integration of wallet functions is your goal.Although, there are some visual annoyances (for example, on Windows, the whole application produces weird window behavior, there should be an epilepsy warning before doing such an operation
), I see that you didn't just fork another Qt wallet, but made a lot of effort towards a better future with Monero.
