Catznip Viewer

No Kitty magic in this one, but it does bring you 'Bakes on Mesh' and is up to date with the current Linden Lab viewer (with some minor bug and crash fix sprinkles to make it complete).

Bakes on Mesh (BoM)

(Note that even if you don't plan on using BoM you still need a BoM-enabled viewer to see others correctly)
