Here's how to color-code sources from Gemini Notebook, formerly NotebookLM, and add a private note to each, in the Kortex Workspace. Open the Workspace with the Dashboard button in the side panel, then choose Sources. Find the source, and click the color dot beside it.
The Source Details panel opens on the right. Under Row Status Highlight, pick one of eight colors. The row takes that color.
The gray None circle clears it. Type a note under Personal Notes and Thoughts. Markdown works.
Then click Save and Sync Notes. To find them later, add the Highlight Color filter, choose Highlight is, then tick the colors you want. Color your sources, and keep a note on each.
