Speed things up by having pre-ser order and return comments available on the Order Info and Returns screens in the admin.
I wrote this extension for my own store as I had some long order comments that let my customers know at what stage of manufacture their order was at. Bored of typing or copying and pasting, this extension was created and made life so much easier.
The comments are managed from modules (Extensions > Modules). You can create any number of comments in the admin modules and they are then availble to you in your choice of either buttons or a dropdown box.
You can set your own Titles for the buttons/dropdown so that you can see which button/dropdown adds which comment.
Opencart 2.x: upload the files via FTP. Requires vQmod installed and working.
