The first version was a single "empty" atom, now it is a scene to merge load The reason for the change is documented in resource description notes and questions area. Suffice to say, this is now a lot more flexible regarding expansion, customization and preset loading.
Audio feedback possibilities I like the idea to use some sort of SFX or voice feedback when pressing the macro keypad buttons. What about a Mortal Kombat voiced "Finish him/her!" when you press the button assigned to the cum triggers?
