Hello Jaiendiran,
We are currently working in features like:
- column group
- freeze column
- add/remove rows
- customize context menu
- new column type to allow links and actions
Our goal is to do a stable release in mid February. It is not confirmed but we would like to have a preview version marked as "Under development" before that release.
Saving configuration is in our backlog, we will be working on it, but won't be available for the next release.
Hopefully this can fit your project's timeline.
Thanks,
Bruno Martinho
