Boo!
Sorry for the late reply, but we've been preparing 2.0.0-rc4b.
Your screenshots look great, let's say a couple of things:
a) Yes, I hate search page at it's actual state. We all do.
b) Somehow, some of your GUI screenshots seem to waste space. Really. Specially the servers one.
c) The buttons on toolbar should have text, I know ;) They ahve on all other platforms, on Mac it's a wx bug and that's why they don't have. Will be fixed as soon as I have time ;)
d) Yes, we'll have compressed images available once the beta is somehow usable.
And now for the main problem : Designing a multiplatform interface. aMule's interface is half done via wxDesigner, half hard-coded. You know how evil would be to code a full interface just for Mac? But maybe is worth the effort :) Anyway, only after the first Mac stable version is out and running.
I haev to say again : nice job! Is there any way you can join #amule channel on irc and talk to me on realtime? I want to make some proposals to you.
