Pierpaolo,
There's no display mode in QRecall that will give you exactly what you're asking for.
The closest I can suggest is to set the bottom shader so the last layer (7) you are interested in is visible. Then set the view options to "Show Deleted Items" and "Show Timelines." Then look at the timelines for each item. Timelines of deleted items that end in the pervious layer (6) were just deleted. Timelines that include a tick in layer 7 were recaptured in that layer.

That's great news.
