I would like the ability to manually select the sentiment of a link that Trackur found. The options should be positive, negative or neutral. I should also be able to filter by these options. The filter should include a "N/A" option in addition to the positive, negative or neutral options so that I can see which ones I have not tagged.

Another feature that relates to this would be a chart that shows the sentiment overtime. Maybe as an option to the existing chart that shows how often you have been mentioned. So you can add or remove the sentiment from the chart.
