We are using the custom quotes beta and very happy with it. Two requests after extensive use:
1) Please allow us to order the templates. Currently the templates show up in the order of "newest created to oldest" which is an odd ordering choice but also means that if we make a new template, our sales team has that as the first option (and invevitably somebody chooses it without paying attention)... See screenshot:
2) Please allow us to make quotes available to specific teams. For example, my account management team should not have access to my "New Business" template and my Sales team should not have access to the "Renewal or Expansion" template.
3) Please make some sort of variable available on the quote (even via API if necessary) so that in workflows (even by using custom code if necessary) we can identify which template was used.
4) Please add the concept of an "Approval Team" whereby anybody on the team can approve a quote rather than requiring a single person to do approvals.
