A simple versioning in the same way that occurs in workflows, so we can not only test our modifications but also do a quality control and not affect the dashboards that are in production.
In addition to the increased safety and reliability to modify the blocks and testing the other new features of losant.
Thanks for the feature request 
I just created a ticket within our system, and in the future, we’ll be sure to let you know if this one get’s released!
Would love to see this!
Hi there, am I right to think this wasn’t implemented? I don’t see any updates on the “Platform Updates” on the blog (albeit I scanned it pretty quickly). I agree with the original poster that this would an excellent feature as it would give us the ability to experiment with our dashboards without affecting customers.
Currently it seems the only workaround would be to have a pseudo-customer that we experiment on and then attempt to make those same changes to live customers once we’re satisfied. Thanks!
No, this has not been implemented, but I will add a +1 to the feature request.
