Numberize Numbers
Feature to insert comma's (or delimiter of choice) into long numbers so 10000000 can be changed to 10,000,000
Just gotta make sure to keep them only to the left of the decimal. So 10543.3456 only becomes 10,543.3456 and not 10,543.3,456
EDIT: Maybe could call it "Commatize" (lol) and put it right next to "Monatize".
