Feature Toggling

From Wikipedia -
feature toggle[1] (also feature switchfeature flagfeature flipperconditional feature, etc.) is a technique in software development that attempts to provide an alternative to maintaining multiple source-code branches (known as feature branches), such that the feature can be tested, even before it is completed and ready for release. Feature toggle is used to hide, enable or disable the features, during run time. For example, during the development process, the developer can enable the feature for testing and disable it for remaining users.[2]
Continuous release and continuous deployment provide developers with rapid feedback about their coding. This requires the integration of their code changes as early as possible. Feature branches introduce a bypass to this process.[3] Feature toggles are an important technique used for the implementation of continuous delivery.
The technique allows developers to release a version of a product that has unfinished features. These unfinished features are hidden (toggled) so they do not appear in the user interface. This allows many small incremental versions of software to be delivered without the cost of constant branching and merging. Feature toggles may allow shorter software integration cycles.[4] A team working on a project can use feature toggle to speed up the process of development, that can include the incomplete code as well.
I have been looking at implementations to accomplish this and came across Togglz - Features flag for Java.   Looks pretty easy to use.   This looks interesting as well Togglz aspect with Spring Boot - Insane Programming.  

I am looking to try to implement feature toggling and would be interested to hear about your experiences.
