I like that you can use it in almost any language or platform (web browser). It's easy to create new projects and tasks using drag & drop functionality which helps me keep track of my work progress easily. There are no specific features i dislike about this software but if your looking for something simple then ganttpdate may not be what you're after! If you want an online tool where you don't have access to desktop applications such as Microsoft office etc.,then look into this product - its very good value for money compared to other similar products out there. Using this program has helped us manage our daily workloads by creating task lists and tracking them via dates / start date and end date.
