The ability to track and measure the growth of a segment on a daily/weekly/monthly basis.

I would like to be able to group multiple events together in a single API call. This is useful when implementing Vero in a mobile app, where it is preferrable to avoid opening too many sockets.

Build a content editor that enables you to edit and re-structure campaigns without touching HTML or creating multiple "layouts" using Vero's current template engine.

Add the ability to see which push tokens fail to send a message

When using a branch node in a workflow, add the ability to take customers back to the main path. This would reduce the need to replicate parts of the workflow in many cases.

Trigger Workflows based on email events, not just the events that you trigger manually.

Ability to add leads in Facebook's custom audience within Workflows. Use Case 1: When someone signups for trial, he gets added to the custom audience where we show relevant ads to nurture that user for the next 30 days and try to convert him into a customer. When the trial ends after 30 days or the user becomes a customer, he is removed from that custom audience and added into a new cutom audience where "nuturing for customers" ads starts to show. Use case 2: Contacts with abandoned cart event are added into a custom audience where we show ads to get them back to the cart.

Add the ability to setup an A/B test "branch" and view the test results within a workflow.

This could be based on the IP used to last open an email.

Have the option on Vero to choose which kind of data should be sent to Segment.
