Add-on What happened to Additional Tools for [Tihnte] XenTag?

We're trying to further develop the already useful XenTag add-on and on our development forum we've got an ""Additional Tools for [Tihnte] XenTag" by @Dinh Thanh that is now nowhere to be found on Xenforo or it seems the rest of the web.

Anyone know what happened to this or why it was removed?
