As much as I'd love to get it done as soon as possible, I'm sorry I probably won't be able to submit the next version until March (maybe mid). If anyone could help improve this, I'd be very grateful, otherwise I'll have the next version done by the end of March (as a promise), and also try it in x86 platform. Sincerely apologize!
