luceos Hahaha it's mostly because of my English. Apologies. Let me put it this way:
Someone creates a discussion saying: "Hey your website has this bug with this error". Then you classify it into TODO.
After that, someone from your staff knows how to fix it but doesnt have the access/privileges to do it. So in order to make profit of time, this staff member creates a comment inside the board (avoiding everyone but staff knowing/reading the fix in case there could be some private info), with the code/message/stepts to fix it and wait for the responsible person to accomplish that.
EDIT: Or, if the case is that this extension is intended for anyone to read and keep track of the progress, then my suggestion might be a little bit dumb hehe. I was thinking on a more collaborative and secure environment where staff could share some private info in a comment textfield.
