Hi there,
Small bug, I believe: when simulating a layout in which I added the ** dead key to two keys, one of the keys gets the second layer from the first key. I.e. when I press the corresponding key twice, both keys produce the same result, although I initially wanted two different behaviours.
For example:
Key 1 has this
** a
Key 2 has this
** b
Well, both will either output a or both b when pressed twice. At least that happens in the simulator.
The shift layer works as expected.
All the best, and thank you very much for this great software!
