In the app pages, values automatically align to left, center or right based on value type, which can be useful for differentiating value types. However, I believe there are times it would be useful to be able to manage all line items alignment to the same setting of left, center or right for readability purposes. This is especially the case when the column width is automatically set across the entire screen. Due to the need to sometimes but not always display multiple columns you may set the grid size larger than necessary for a single column.
