Following up on the previous "differences" topic, the new SeedCode Complete adds a few things to SeedCode Calendar which we released last year...

Invoices: we've added a simple invoicing component which now lets you invoice projects and/or contacts.

Mailings: you can now send bulk mailings to a found set of contacts, contacts' projects, appointments or invoices.

Navigation: we've replaced the hard-coded Photoshop tabs with a dynamic tab engine that makes it much easier to add new tabs and layouts. We've also built in BackMagic, for browser-like Back and FWD buttons

Speed: While the scheduling component remains pretty much the same (though we have made the 15 minute scheduling increment adjustable from 5 min to 1 hour), the calendar is faster. Oh, and the horizontal scheduling view is much improved meaning this version of the calendar does a great job scheduling larger numbers of resources.
