Actual Start and Actual End date columns
It'll be helpful to track the actual start date and actual end-date column and how it'll affect the start date and end date once the project has been baselined. Very essential feature and will prove to be one of the worthy functions of gantter. Anyways, really like and appreciate this system so far.
You can do this from a baseline created on the top toolbar. Please remember a baseline is a stamp of your project at the time of creating. You can create multiple baselines to view.
