iPad Chat Overlay - copy the functionality available on iPhone Twitch app
Add to Twitch iPad the same Chat Overlay Customizations that the Twitch iPhone has.
On the iPhone Twitch app, while watching a stream, you can turn your phone to landscape mode, click settings, and there is an option to click Chat Overlay Customizations such as Adjust Overlay Opacity, change the chat vertical position, and chat horizontal position.
There is also an option on the iPhone to change the way the Chat Switching Shortcut button works to toggle between Chat Overlay, Column Chat, and No Chat. This feature is not on the iPad.
I like to chat in streams on my iPad, but when I click into the chat box in iPad, it makes the chat area wider while making the stream video player smaller. I wish the overlay feature was available on the iPad like it is on my iPhone.
