This would be very helpful to visualize breaks of specific tasks. For example if there is a vacation, or the client/partner comes back with new tasks after it ended.

I created this mockup in Krita with a scissors material design button and did dirty copy pate of timeframes to visualize it.

Alternatively, you could also right click a task and then select (split task).

Would be good to know what could be broken in Kitsu/Zou currently.
