Problem to solve
We want a visual way to differentiate calendar dates on the Timeline, in addition to the left-positioned date indicators
- All edits that are made on the same calendar date should appear inside a new background element
- It is Fine if the box has to readjust due to infinite scrolling
- Use the colors depicted in the wireframe
This might take some restructuring of the HTML. Instead of the date being part of the "row" it will need to be it's own wrapper. This means the revisions might need to be broken up into map of Date -> List of Revisions. But I would just do that within the component (or within a selector, which is memorized).
