Hmm...a little frustrating having to create the same custom template twice. Will this be implemented, either in Invoice or Totals2?
Also, on another note, I have noticed that there's no way to import customers in bulk from Address Book, which, again, having to create 100 customers one at a time seems a little inefficient.
It is already implemented in Totals 2. You can export/import and duplicate Layouts in Totals 2. We don't add new features to Invoice 3, instead we add them always to Totals.
We hope to introduce an upgrade path at the end of this month. Please drop me an email or private message when your 15 days trial is over before we introduce the upgrade path. ~Ferhat
