I was thinking of purchasing this add-on before programming one of my own.
Now that facepunch is going to integrate a more decent first person camera I thought it would be great if while specifying players to see their UKN-style rollback pattern, which your plugin already does using a command.
I wonder how difficult it will be to make it compatible so that it automatically activates on the player you are viewing. I don't know if there are any kind of hooks in oxide that can help with this task, but I certainly think it is an interesting feature to incorporate.
I leave it there in case you want to give it a spin and implement it if you see it possible. Otherwise I will try to find out on my own once I buy it later.
