As a user, when I'm navigating on a Node Graph, having my Sidepanel opened and focusing some nodes, I can expand/hide each info section. This feature has been added to reduce the waterline, so that I can see the extracted articles even with a reduced screen. I want this action of toggling to be stored, so that I do not have to repeat the action each time I'm opening a Graph

Coding steps

• add a new JavaScript LocalStorage entry
• the value could be factorised for a Node Phylo too, as the Data tab is identical
