I’m finding that often when I create a task, users are raising multiple related points that need individual follow up. It’s easy for these to get lost in an active thread, despite best efforts to word tasks so that we try to avoid this.
It might be a great idea to have an option to convert a comment or reply to a task into a subtask at the click of a button. It crystallises discussion in the main task and creates a dedicated channel for it.
It could even be extended to allow the moving of other comments in the thread that relate to that same task to an existing sub task.
For example - three users start talking about an action better tracked as a sub task. You click the original point and convert to sub task. You then checkbox or individually select additional comments from that thread to move to the sub task.
We grey out those comments with a hyperlink to the subtask tracking them all.
This would create easy de-threading and enable focus to remain on the core objective of the main or sub task.
