+We are currently investigating the overall browser performance impact of this, which is why the first implementation is what is shown in the screencast above and doesn't feature any interaction with the JSON payload beyond collapsing nodes.
 
 ### Goals 
 
 As JSON files are data structures and users want to drill down into the data and analyse it in detail. This is a first step in this direction. In subsequent iterations we want to add more functionality like displaying header data and a raw view, saving and copying data and filtering the information.
 
 ### Usage 
 
-This functionality will trigger automatically when the browser navigates to a JSON file on the web or the user opens a local one.
+This functionality will trigger automatically when the browser navigates to a JSON file on the web or the user opens a local one. Once we add more features you will also be able to interact with the JSON data in more detail.
+
+### Feature release plan
+
+**Current:** JSON is being displayed as a collapsible tree with line numbers and colour coding in dark and light themes
+
+Upcoming features in delivery order: 
+
+* Get a "slow" warning when the JSON is too big to render and an option to show it as plain text instead
+* Get an "invalid" warning when the JSON payload is invalid
+* Switch between the expandable tree view and the raw text view
+* Copy the JSON payload with a button
+* Download the JSON payload with a button
+* Search/filter the JSON
+* Expand and collapse all the nodes in the document
+* Choose to display JSON in table format for array data that can be sorted/filtered
+* Large JSON payloads will load the first 500K and then offer to stream the rest
+* Choose to inherit themes from DevTools
+* Set Raw or Tree display as a default
+*  Open JSON in Network Console
