tabbed window(s) explorer - clover done right by stardock

Just a observation,

Of all of the many productivity tools Stardock has created for a better MS Windows experience I cannot help but think why does Stardock not offer a tabbed windows explorer experience similar but better like EIJE - Clover tabbed addon.

I believe Stardock could do a much better Job than this Clover implementation. For me such an addon would be worth 15 euro per license per machine.

Not sure what others think about this.
