Build table-of-contents-style panel to house notebook output cells

[juliahuynh]

Problem

• Having notebooks alongside dashboard editor creates a spatial problem
• On smaller screens, dashboards can become hard to navigate and edit since the majority of the canvas is out of view

Proposal

• A table of contents style (ToC) panel that imports output and markdown cells (potentially code cells) from notebooks
• ToC panel will house output cards that can be dragged onto the dashboard canvas
• Full notebooks will not need to be in view in order to add outputs
• To use outputs from different notebooks, click the drop down at the top to browse available notebooks
• This solution will solve the workspace issue by taking up less space on the screen
