Batch Delete
I changed the prefix for a backup source without deleting it
this created a state where there were several hundred "orphaned" archives, that would not be automatically cleaned up (owing to the old prefix)
Please consider adding a "batch delete" ui, so I could select a range of backup archives or several individual archives (checkbox list select), then delete them all at once
Without this feature, I have to delete them one-by-one, waiting for each delete to complete before I'm able to move on to the next operation.
