Hi - the Gantt chart is really useful but for complex projects it could do with some further features which I don't think are included already:
1. If a project spans multiple years (i.e. 2019 & 2020), then it would nice to be able to see the year next to the month in the header fields.
2. It would be nice to have an option to summarise the columns into weeks, months, or quarters as suits the user, so that large projects can be snapshotted by (for example) quarter.
