One cairo dock for each screen of the system

It would be nice to have a cairo dock in each window if u have multi monitors in your system. Actually there is a single config for all the docks of a sesion.

In the settings you can't have two docks, only one, you can choose in wich screen or share half and half but not have two of them.

You can cheat and exec two times cairo dock, and move one of them to the left and the other to the right screen but it uses one config so is not working properly,a dn after restart only one persists.
