I haven’t gotten the 3.1 update working quite right yet due to the ongoing MediaCloud problem, but I must admit, the revised app naming and layout of the AppleTV menu is great! It feels way more native and “Apple” now.
One suggestion: It is not mentioned in the documentation, but it seems you must be logged in as an Administrator to create the patchstick. I tend to run as limited user for security reasons, so my preference would be to not have to run in the Administrator instance on the Mac for install and just simply fill out the Admin username and password from within the limited user instance. This seems to be more within Mac design, as many system changes are allowed within the limited user interface, as long as the Admin username and password are given at the prompt.
