Create button before Create and Import in odoo v11
I search a lot in the web, read the odoo docs, but I can't figure it out how to add a button before "Create" and "Import" buttons. I found many solutions in other versions (v8, v9 and v10) but none works.
The result should look like this. And the buttons have access to python functions.
