First up is screen recording and live screencasting. To start this, you just hop into the YouTube Gaming app and choose the "Go Live" option from your profile. After choosing if you want to record in 480p or 720p and adding a name and description, floating action buttons will pop up to let you record. While recording, you even have the option to turn on the front-facing camera so everyone can see the intense concentration on your face as you try to kill lizards in Nibblers.
The watch later list shouldn't need any explanation, both because it exists in the standard YouTube experience, and because the explanation is in the name itself. It's a list... where you watch videos... later.
Lastly, there is also an import tool, similar to the one you would find if you were to go to YouTube Gaming in your desktop browser. It basically searches your YouTube subscriptions for any channels that may include gaming content and lets you import those to YouTube Gaming. Pretty straightforward and useful.
The update is rolling out now to Android users.
