The solution seems very polished! Nice work! -- offtopic: I'm working on something similar as well, but Toggles/Feature flags is "one of the parts" of the solution ( it's more a full blown development tool for handling settings, centralized services (eg. e-mail) and much more -> Eg. a support tool with forms which can be prepared by devs) It's currently only dotnet ( and MVC) based though, but it's working.
