VIRTUALTAOIST  I would also like to see this fantastic app running natively on Mac OS X, from what I have researched, progress is being made, but like alot of things in the Open Source Community it's going to take alot of time due to Mac OS X being still treated like a minority operating system compared to Windows, and most developers preferring to develop for their beloved Linux, yet they fail to realise that a huge amount of creative agency's and freelance digital artists/designers use Mac OS X. I hope work can be speeded up on the OS X native port of GTK+ as I would love to see this and GIMP running natively, if I had a shred of knowledge about programming I would help out, but sadly I don't, I'm just an artist :P, so come on software engineers! theres alot of creative people with no knowledge of programming out here needing you to get this working as soon as possible! and to stop treating our favourite platform like a second class citizen!

VIRTUALTAOIST  AVOID THIS APPLICATION:

I am sad to say that this application has to be considered malware as far as I am concerned, I never even got to use the application because it would not activate without me "Registering" for some Sims3 fansite in order to help the author of this program gain some kind of status, this is a clear attempt by the author to utilise other people information for his own personal gain, regardless or not if it himself or a 3rd party that the information is being submitted to, the application also would not close down when I tried submitting a false email address and name, and I had to use the activity monitor to forcefully close the application.

Once again, avoid this application like the plague, I registered just so I could voice this criticism of this software authors shady practices.
