I find timestamps help me with rebuilding my thought process when I’m doing interstitial journaling, but I don’t try them as the beginning of a task, but as the moment when a reflection starts. I would like to combine interstitial journaling with checklist, but seems that @Mohammad’s Kara has not (yet) support for it. In that way the timestamp can mark the initiation of a task and the checklist just mark the completion of its subtasks. Maybe when a checkbox is crossed, a timestamp could be added, but I will be fine with just timestamps for entries and checklists for subentries.
