Simple Cloner is a module purpose built for Expression Engine 3 which allows users to duplicate channel entries from a tab in the publish layout. Suffixes can be appended to the title and URL title fields in EE to differentiate cloned entries.
If you are working with bloqs I have noted that you will receive a PHP warning on PHP 5.6.25
Invalid argument supplied for foreach()
A simple fix for this if this issue happens to you:
Navigate to system/user/addons/bloqs/libraries/EEBlocks/Controller/PublishController.php line: 502
foreach ($data as $row_id => $blockdata)
foreach ((array) $data as $row_id => $blockdata)
