The ability to add various columns to a given subform is brilliant and very useful but the inability to not adjust the column width or be able to freeze the first columns limits their use as one can the row identifier one is changing. One of the challenges of the many columns in the subforms is that one can not tell what row identifier'a field one is changing.

FREEZING COLUMN

For example, in a Quote module we might start with the product and then several columns to the right there is a field that requires input, we can not tell which product it is - ie product XYZ has a remarks field that one has to scroll to the right to see, when updating the remarks field one does not know the related product and can be adding remarks to Product ZZZ instead of Product XYZ.  The ability to Freezing the first (or more columns would be REALLY useful. 

ADJUSTING COLUMN WIDTH

Being able to adjust the column width would help a little with the viewing of fields.
