Feature request: Add a "copy to task..." feature inside the 3-dots menu on comments. This would be similar to the Ctrl+K menu where you could search for a task where you'd like to copy the comment to. You'd have the option to "copy-paste comment" (this would result in a duplicate of the original comment, ie. a living 'mirror' of the original comment that can be replied to in either location - the equivalent of having a task live in multiple lists?) or "cut-paste" comment (removing it from the original location so that the only active version of the comment is in the new location).
Use case 1: team members post comments inside sub-tasks while they work; near the wrap up process, we want to easily move the most relevant comments from the sub-tasks into the parent task, so they can be easily reviewed by a manager, who is the assignee on the Parent task. Manager does not want to have to drill into every single subtask in order to review comments. This would be ideal for "mirroring" comments (moving a 'mirror' version up to the parent task).
Use case 2: you write out a nice long comment, then you realize you put it on the wrong task and you want to move it easily to the correct one. This would be a use case for a cut/paste action.
