1.) Is being able to apply dependencies in the GANTT view by visually connecting tasks. Having to search for them in the list of tasks is way to time consuming. All GANTT programs allow you to visually connect tasks.
2.) The automation of dependencies being pushed forward based on a change to the previous task date takes way to long. I could move the task in GANTT view manually faster then the automation can, it usually takes a while for it to even start the automation.
