A number of Tinderbox's utility views use the $MapBackgroundColor of the TBX to which they refer as an accent colour for the view (Note: it is always the document level setting colour and not that of the current note/container). Currently, this change affects these 'utility' views:
In the case of all but the Roadmap the accent colour is used for the background of the list area - but only for listed matches. If the list of matches doesn't fill the list area, the unfilled area is coloured white.
In the Roadmap view the accent colour is used to shade the current note icon top centre of the view and both side lists.
