You can easily duplicate any record on both Records page and in table widget
One more feature request has been implemented. This is a Copy or Clone Record feature.
Please, click on 'View' or 'Edit' at the left side of each record on the Records page. You'll see a 'Clone' icon. Please, click on it and this record will be duplicated.
Once cloned you'll be asked to update this record.
Most probably you need a Clone Record feature for copying big records, when the difference between records consist just in several fields, i.e. you have 10 forms fields, but 8 are just the same.
If you don't want to update it you can just cancel editing and you can see duplicated records now.
You can enable cloning in table widget too. Just go to 'Table' in 'Widgets' section and in 'Actions' you can enable cloning.
