Recommended plugin name?

Hi,

When I activated Arba, I could swear there was a notification about installing a recommended plugin. I dismissed it without installing, but now can’t find the plugin(name) anywhere. It’s not in the theme package and searching the internet didn’t get any results. Am I wrong, there isn’t a recommended plugin? Or can anyone tell me what it is and where to get it?

I’m not sure if I get the most out of the theme without it.

Thanks in advance,

Jordy
