Hi,
Please find the attached updated patch.
Feature Details:
- The current tree state as well as the previous will be stored in the
sqlite database.
- The time interval to store the tree state is configurable via preferences
and the default is 30 secs.
-1 can be used to stop the tree saving functionality,
- Jasmine test cases are included.
Thanks,
Khushboo
