This is a minor upgrade from the 2.0 version, which has included fixes for all feedback on that previous version:
Cells now toggle off when pressing the button on them when they are on (and still normally turn on as intended when off).
I tested gliders across all diagonals and they all work fine, and 2*2 and 3*1's no longer break.
Each cell can be turned on using the button in the center of the cell, and the cell can be turned off again by repressing the button. You can use the lever on the bottom right side to start/stop the generation loop, and the button on the bottom left side to kill all active cells.
