Currently tasks create the timeboxes. But that's not really true timeboxing. True timeboxes should be treaed as placeholders instead, then tasks are dragged into them. For example, I can create one timebox for 3 hours that describes the overall goal during that period, like Content, Outreach, Development, etc. Then drag tasks into each timebox accordingly. For example, the content timebox could have tasks like: Research Topic 30min., Write LinkedIn post 45min., Write FB Group Post 25min., etc. Timebox time will not be calculated towards the actual time - they are just placeholders, so that still remains with the tasks. See attached for an example how the entire day is timeboxed. Tasks are not added to keep it clean for the ilustration, but hopefully you get the idea.
