Classy allows easily managing classes in IDA Pro. Vtables can be generated by selecting a range, functions can be assigned to classes, their signatures can be easily editing and mangled, IDA structs can be assigned, C headers can be generated, probably more :)
Credits to Ninji aka Treeki for the core idea and many code snippets from the plugin he created.
