Advanced calendar features
Currently syncing with Google calendar because of the ability to layer with other calendars but would love to have this integrated. Other great features would be to have the ability to "pin" a task, say an appointment that wouldnt move, create buffers around tasks- for transitioning etc, move other tasks that could go around pinned tasks as opposed to overlapping, setting completely customizable work hours and allowing tasks to only fill this time, being able to "push" other tasks when moving a task for rescheduling, and when a task is moved to the end of the work day it would continue any leftover time to the next day

Not enough community interest.

The option to set each task to be pinned, overlapped or pushed would be amazing!
