Number field which permits comma separators
To create an integer number field that allows a number format using comma separators, but where the field is still calculable. For example we use a field Annual Revenue $,000 which when populated for our records, contains 6-8 digits. Comma separators appear in the list view, but not when individual organisation records are open, making the figure difficult to read.
Mark Alston commented
We use large numbers a lot (most clients have usage which runs into 7 figures), but it's currently very difficult to tell at a glance if it's 1million units or 10 million units as they appear as 1000000 and 10000000.
Comma separation is a MUST
