Just started using TWP. Not sure if it's is a good thread to post this but... i built a new theme/stylesheet last night which is available here:

It may not function appropriately for advanced users, but it's tested in Safari 2.0.4...!

(Drop in /var/hack/TivoWebPlus/Themes/ and full restart TivoWebPlus or reboot Tivo.)
