1) just wondering if there is anything we can do with line items? As far as I can tell, they are display only?
Use in triggers or with scripts? (ie, client side total a column and place the value in another field)
2) Advanced fields inline items? (ie. order list, product SKU dynamic dropdown/autofill from our own database)
3) There is a limitation of 2 line item sections for me (not sure if changes with different levels), this should be shown in the "Remaining Fields" section as well because there are no errors or messages when you try to create a 3rd section.
4) Suggestion to +$ to increase this limit and other limits
0) Side note: More users = more limits?
