Saving Screen Space
If you find that the tree on the left is using up too much of your screen space, then right-click on the tree, and hide any columns that you are not currently using. e.g. on the Feed Templates tab, you can select Digestibility Group Column Visible to either hide or display this column, as shown below.
Between the tree and the details section is a bar that can be used to resize each section. In the middle of the resize bar is a section marked by a dotted line, shown below.
Clicking once on this middle section will move the bar completely to the left or right, depending on its current position. This is a lot faster than dragging the bar across. e.g. when editing a feed, position the bar between the nutrients and ingredients so that all nutrient columns are visible. Then, to see the ingredients section, click on the middle of the bar, and it will move to the left, making the ingredients section visible.
