I found Caps as Backspace quickly felt natural and much nicer than the traditional Backspace key, it's great to have this frequently used key close by and not have to move a hand off the home row.
That said, having the arrow / cursor keys under the home row via a mod key is also super appealing.
I'm torn between these. I suppose I could put backspace in that mod layer, maybe make it Caps-A so its a nice roll of adjacent keys similar to just striking Caps with the pinky.
Any comments or suggestions?
