Calibre does not warn about 'inaccessible' books not added
Platform: Mac Snow Leopard 10.6.8
Calibre: 0.8.11 or older
If I drop a bunch of pdf documents on Calibre to add, it only adds the one it has permissions to add and silently ignores the rest. The user is not notified if one or more documents got skipped. If 10 books were dropped and 9 got added, the user won't be any wiser and think that all got added and (At least in my case) proceed the delete the original causing data loss.
