### Description Redmine has a concept of activities that lets you add time tracking on an issue for a specific activity in this issue (designing, testing, documenting, and other non-strictly programming activities).  ### Proposal | Add `@user` and `message` parameters to optionally spend time on behalf of someone else/add a related message | | --- | |   | | User adds time spent, the optional user, and the optional message | | --- | |  | | The system note shows up with the message below it and indented (reusing styles from discussion comments) | | --- | |  | #### Design notes * The indented message should reuse-styles from `Discussion` type notes * If a user clicks `Start discussion` when inputting the quick action, everything should act just [the same](https://gitlab.com/gitlab-org/gitlab-ce/issues/42537#note_94906392) as if the user clicked `Comment` (exactly how the other quick actions work) Reference: * [comment on hacker news](https://news.ycombinator.com/item?id=13023614) * [Redmine on the topic](http://www.redmine.org/projects/redmine/wiki/RedmineTimeTracking)
