allow a REFRESH-ALL messages when you make edits to a template.
Once you edit a template, there should be a single-click option to refresh all messages that are currently using that template. Some templates can be used by hundreds of messages, and they should not have to all be opened individually in order to click on 'Refresh'! Thanks!
We have no plans to implement this at this time due to the dangers involved when refreshing template code. It can result in full loss of message content, and individually refreshing messages requires that you approve the new content. The template system is changing with the new Message Editor (currently in Beta), so give that a try and keep the suggestions coming!

Great idea! I would love this feature to apply to template tags as well. I store coupon codes in template tags and need to update those every couple weeks. It really is a pain to update a common variable in one place, only to have to update every message and template that contains an instance of that variable.
Instead of having to go into each message after a template update, allow for a refresh all button. The same with content boxes. This will allow for better content management.
