I read in a thread that has been buried a bit that the dev team has mentioned adding another set of 8 actions to the crossbar so that L2, R2, and L2+R2 all map to 8 options. This will increase the number of actions that players can easily set by 50%.
I have not been able to find evidence that the dev team actually said this, but I would personally love this feature or option.
Can anyone confirm/deny that this was discussed?
