I've had a chance to look at this gem. Its documentation is pretty extensive which is always nice to see. I'll consider covering this gem in the future. One thing that I highly dislike about this gem is that it seems a lot more invasive in the models. It also has a lot of added complexity based on the documentation and I'm not convinced that it's necessary to accomplish what they're doing. Overall the gem does look pretty cool and for a large complex app, this may be a good fit.
Yea, I could do a video or blog post on how I set up my editor. It's overall fairly simple, but I do have some things that I do normally that others may not.
In this situation, the developers must have access to the master key which would expose production secrets to more people than necessary. This of course depends on the layout of the R&D team. If it is a solo developer working on a personal project then the exposure is obviously limited. However, in a larger setting, often the developers will not have access nor the secrets to the production environment.
