Have proposed creating iiif-commons/iiif-redux on the IIIF softwaredevs slack channel.
This should be a community effort that allows for viewer-role-only state management that can be extended via combineReducers to more sophisticated use cases like content authoring.

The UV would replace its current pubsub system that uses https://github.com/edsilv/jquery-tiny-pubsub with a redux store inside manifold. Events like CANVASINDEX_CHANGED would no longer be emitted within the UV - rather an action would be called on the external redux store which would trigger an event listened for in the UV.

Will need to categorise https://github.com/UniversalViewer/universalviewer/blob/master/src/modules/uv-shared-module/BaseEvents.ts into generic IIIF events and UV-specific events. The UV could extend the generic IIIF store.

@edsilv, is this still work in progress, or is this something we should close or clarify? I'll mark as active until you have a chance to answer.
