A Kanban view can help me focus only on Morgen and leave Notion task management. Having it can be a moat against Notion Calendar, which should integrate both calendar and task management into one ecosystem (Notion). Having a slightly better task management with a kanban view and swimming lanes can reinforce your value prop and raise competitive advantage over Sunsama, Routine, and Motion.

A board/kanban view, like in the motion app, would help me migrate from other tools to here. Even if with a basic view.

+1 on the kanban view option for tasks except I think it would be more helpful to have as an option to view them by date so you can plan ahead and easily drop tasks on your calendar for a specific day in the future but not yet ready to time block it on the calendar. Sunsama does a good job at this. Right now you can do this by dropping them as all day events on the calendar but the experience is not great. A quick fix may simply be the ability to drag and expand the all day event section to make it bigger which might work well rather than a dedicated view.
