Me.Class.ShortName should be in there by default already so you probably don't have much need for Me.Class. The overview page has some screenshots of how to add things, but to summarize:
1. Add a property which you want to observe. This would be a TLO member like Me.Class. Don't include the ${ }.
2. Add a column which references the property. The column define things like thresholds for coloring the text if its a number, whether the values ascending/descending like if you want 0 to be red and 100 to be green, etc.
3. Add the column to an existing tab or create a new tab. A column can be added to one or more tabs, in case you wanted it to always be visible on all tabs or something.
