It is time for the final release. I couldn't include the all features that were requested, unfortunately. I've fixed some minor bugs which went unnoticed till now. Exporting of multiple files and directories has been added. And, I've added command line support to the editor with support for extracting and replacing files. I haven't included automatic importing of files through the user interface, as Kshitiz has said he wants to develop an auto mod installer and manager for AC09. It should make installation of patches easier. You can also create your own mod installers, if you can program or know how to create batch files. Details on how the command line parameters work are in the readme file.
I don't have time to release any more updates, but if there are any critical bugs then post a detailed report and I'll try to fix them asap.
