Same, but the author is working on a new project now.
Really though - a number of features (not all, but some nice ones) in this mod are already in Warband for free. Ex. showing horse HP, or upgrading all troops at once.
What would be useful would be to reverse engineer how to add certain useful features, and then to figure out how to add them into Warband mods. Even better, provide instructions to modders on how to do this in native so they can add them to their mods (since most mods don't include source, it's the only way).
