Multiple recycling bins for different synced devices
When syncing a folder on a PC for example, based on the type of folder that is synced, many little files might get deleted and move to the recycling bin regularly, where every other deleted file needs to be searched in the flood if you wanted to recover it.
If there were different recycle bins, like one for the main drive, one for device 1, one for device 2..., files that you want to recover would be easier to find, as they are already sorted in a simple way.
Alternatively, if you could filter by paths in the recycling bin, this would be solved as well. Currently it seems that you cannot do anything with the path attribute. You can sort by any other attribute (name, deleted, size), but not path.
