This is a great plugin, I love it, however I did find that it doesn't duplicate everything. Say I have Gravity Forms installed, when I duplicate a site, it doesn't copy the tables GF creates. This happens for a number of plugins that create their own tables for a site.
What would be great to have is if the plugin could duplicate every table within a multisite that has the same site ID and put that in the new site. Would be a huge time saver! My only work around to this so far has been to export these missing tables and change the site ID's so I can reimport these tables into the new site :(
Thanks for all the work on this awesome plugin, would love to see this feature added in the next release!
