Thank you for showing some love to the older version of this custom workspace. I've uploaded the newer version of this workspace on ServiceNow share keeping the feedback in mind.

Download the latest version here.

New Features:

1. Refreshed UI.
2. Now you can remove permissions from reports as well while removing permissions from dashboards.
3. Now you can set your default tab on launch. Can be set based on user preference.
4. The workspace is now locked only for Admin users. It is recommended that this should be only shared with admin users due to some potential permission issues.

Bug Fixes:

1. There was an error which caused multiple records creation while sharing a report with a user or group to which report was already shared.
2. Dashboard sharing permissions were not cascading to the reports earlier. This has been fixed.
3. The logging has been made better for debugging.
