Description

As a Node-RED Developer and FlowFuse User,

I want to have the ability to directly access other FlowFuse menus from within the Node-RED Editor,

So that I can maintain awareness of being within the FlowFuse environment and have the flexibility to not just return to the previous menu but also to navigate seamlessly to other areas of FlowFuse.

Which customers would this be availble to

Everyone - CE/Starter/Team/Enterprise

Acceptance Criteria

• [ ] The left main navigation bar within the FlowFuse interface, when in the Node-RED Editor, can be collapsed and expanded by the user, allowing for more screen space when needed.
