Feature Request: Detect duplicate tabs in a group

[gopalagrawal]

Have several 100's of tabs in some of my groups. Would like to weed out the duplicate entries that eventually will happen after many days of use. For example: If I open a group with 300 tabs ... I'm then browsing/reading/youtubing ... and I open up more links (some of which I had likely opened up a few days ago in this same group but don't remember anything about those links). Then duplicate entries are created. After going through one of my groups, I found that almost 10% or more tabs were actually duplicates I inadvertently created.

Perhaps some button alongside a group which scans for identical URLs and asks user to manually confirm to delete the duplicate entries.
