We'll see how the physical page turn buttons will feel. I do not like how the latest Kobo release made the buttons closer to the edge. I have a Sage and miss the nice feel on the front of the Forma and dislike the page turn button placement movement. These.. are literally on the edge
That being said, Goodereader's article that has the above video as an embed did have this tip.
"... if you hold down the home button down for two seconds it will give you options to control the lighting system and a single tap will take you to the library"
Can confirm with the GlowLight Plus I have, holding down the home button for two seconds turns off and on the light. So a little bit of an update there.
