Photo proofing criteria

Hi,
I’m looking for a proofing plugin and I’m not 100% sure yet that yours meets my criteria. Could you please comment on these questions I have?:
1. Does your plugin offer a login for clients with username and password (I prefer having a username login as opposed to showing a list of all my clients where they then have to pick their profile and only input their password, as the former option is more discreet)
2. When a client chooses some pics, is there an option to bulk download them in a zip file or how do they get them?
3. Is there an option to receive notification once a client has downloaded his photos, and how many and which ones he chose?
Thank you very much,
Michaela
