Additional functions to add when pricing an item in fm so you don't always have to mentally count how many zeros you placed, for example: Pressing a button will just paste that value in to the "PRICE PER ITEM/BUNDLE" section while keeping the price check marked, and you'd still need to press okay. Changing the price manually will uncheck the box. Hopefully the buttons are adequately apart so they won't be that easy to mistakenly press the wrong price. Another way could be addition of commas between every 3 sets of zeros numbers during pricing of the item
It is probably easier if you can enter a number along with selecting an alphabet (such as K, M or B). Such as "1" + "M" = 1,000,000 or "2" + "B" = 2,000,000,000. The code can be either converting "1M" to the actual amount or inserting how many zeroes based on the selected M or B. The "auto price" shown above is likely not very applicable to everyone (prices that are not listed above). The need for manual adjustments would still lead to some human errors, such as accidentally deleting too many zeroes upon selecting the default values.
