    1. COThis work great. unfortunately I have enabled the line number to be displayed. So line numbers are overriding the TODO: mark. Any way to make both to appear

    3. COCool! but.....:) ...What would be more useful is to display red bars on the fringe, scaled to the length of the document. In other words, if the TODO appears at the 75% point of the document, then the indicator would also appear at 75% on the fringe bar, regardless of scroll state and whether the TODO was visible in the window at the time. Some diff tools do this. With that sort of indicator, you can see the presence of TODO items indicated in the fringe, regardless whether they are visible currently on the screen.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
