- Reseller-level creation utilities (so resellers can link a system such as modernbill to Plesk for automated account creation, etc.)
- A basic and advanced interface selection (basic including the odd thing such as FTP password changes, mailbox setup - basically a very simple interface for users who don't have a clue, and standard Plesk interface for those who do - controllable by admin/client/domain level)
- Advanced feature selection (such as not showing any of the hosting stuff if we want to setup an email only domain-level account) - similar to button hiding I guess
- Web user control panel access
- ProFTPd SSL patch
- ClamAV (or qmail-scanner style optional antivirus integration so I can use F-Prot) integration (I know it's been said, but I'm in the sort of mood to want to repeat it)
- Easy-to-configure control panel access so that we can serve Plesk from port 443 on a specific IP rather than messing with httpsd.conf, etc. to bind Plesk to an IP for behind-firewall access when 8443 is blocked
- Password-protected directories for subdomains
- Domain vhost and email aliasing
- Domain vhost and email aliasing
- Domain vhost and email aliasing
- Domain vhost and email aliasing
- aww come on ... you know we need it
- Advanced reseller branding (ability to add welcome message to main page of control panel etc.)
- Automated client backups (similar to domain-level, but client-wide)
