Well yeah, it did - I don't remember quite what, but I think it showed the experience rate or something like that. (there was also a hidden feature that showed your login/password in the window title for a short while - I got access to the dll for TibiaGG, which taught me a bit about memory access. This was only done as a prank though, and never for any nefarious purposes)

The software was called Tomes of Knowledge, if that rings any bells :)
