Regretfully, there is no way to vote. But, is the new Template Manager lacking in feature? With it, you can export a whole page or part of a page as a template down to element level as presets. In addition, you can download all of your templates and import them to a new site. In case you did not know about this already, please see our Changelog starting from the day it was released https://theme.co/changelog/#theme-x-6-0-0. Also check out our Knowledge Base for new tutorials such as the Global Blocks feature.
Going back to my reply 6 months ago. Just 12 days after, Kyle released a status report stating that the old template manager will get a revamp. From there, discussion was started which involved users until it was finally released.
