It's main features include:
- 32 & 64 Bit Support
- Multithreading, thanks to wxWidgets
- Cross Platform Support ( Windows, Linux, Mac ), thanks to wxWidgets
- Plugin System to Support as many different Mods and features as possible
- OpenSource
- Tabbed Maps instead of windowed (makes it easier and faster to switch between maps)
- Language Support, again thanks to wxWidgets
(anything else? maybe later... heck I'm still making the Layout

ToDo: complete this post and add screenshots...
