Super themes, bravo.
Wanted to know if it’s possible to edit copyright section?
Thank you for your kind words.
This is not possible in the MT Writer theme at the moment.
You can edit the template-functions.php file which contains the footer code. Just go to line no. 359 and update the line as you like.
We’ll be releasing the customizer control to customize the footer text in our next update, so it’ll be easy for you to edit.
