Please consider making table editing easier for adding/moving and deleting rows.
At present you can change the number of rows and if increasing the number it adds them at the bottom. But what if you need to insert a row? Or move a row from say row 10 to row 4?
If you were able to add a "cog and X" to the outline tree like you have on the pages/service/css tree like the image below then you could easily provide this and simply insert/delete and and other markup as necessary at that point rather than at the end.
