Hi Joubin,
Currently, we are working on some important features like PDF Export, Excel export, Indent and Outdent, row drag and drop support. You can track the status of these features by using below feedback portal link.
The main version Gantt will be released in our upcoming Volume 3, 2019 main release, which is expected to be rolled out at the mid of October, 2019.
Please let me know, if you need further assistance on this.
Regards,
Jesus Arockia Sankaran S
