Hello guys. Very good job.
I want to jump here this feature request. Why? Sometimes, in very big websites, you may need similar ads for similar categories, but having to set all the variables again is a PITA. The same applies to blocks and groups.
So, in the Bulk Actions drop down could be great to have a "Clone" action to create copies of elements. The name of cloned ones should be clearly marked as "Duplicate" or "Clone" and should be deactivated by default, so you can work on it.
Maybe putting the Clone action besides the name of the ad/group/block, like the "Stats" link currently is, could be a better idea.
It's up to you. If it can make thru to the free version, will be lovable.
