Look into creating a helper that registers a boolean flag with the store for simple flags.

Currently the core team is storing all state items in the store. This includes simple flags for loading indicators etc. This requires devs to touch many files to add a single flag.

It would be very useful if there was a helper that could be used that simply registers a boolean to the store. This would likely work best when there is a specific store object for UI flags so that the helper isn't just registering these items anywhere.
