Two screenshots of what I've been busy with for my NXT Solaris client. To be released over the weekend, since I need a rest.

Be careful with the market view, though. You know, it's closed source and I might have something in there that influences the markets in the direction I want...

Indeed, awesome! But for me as most likely for many other people, a closed source client is a show-stopper.
IMO, you're better off rethinking your license model and work around any constraints of 3rd party software.
This simply looks too promising to not receive the acceptance which apart from the license model this quality work surely deserves.
No joke. This open source and for mac and the client issue would be finished for ever.
