I picked up a Kinesis Advantage360 Pro #keyboard the other day but was struggling with what to do with my trackpad.
Way back in 2012 or so I stuck an original Magic Trackpad to my first Advantage2 between the key wells and thus it's been for more than a decade, but that doesn't work with an actual split keyboard.
Piecing together a few ideas I found on Reddit, I picked up a MagSafe-compatible phone stand and a steel ring sticker. Apply sticker to back of trackpad, magnet it to the phone stand, ✨ ergonomics ✨.
We'll see how long it lasts wrt tension in the stand's joints. Hard to say if it's super stiff just because it's cold.
