I'm working on a new loan calculator plugin - this one is aimed at those who set a rate depending on your credit rating. I know people can lie but that's not the point of the calculator. The question here is: What parameters/styles would you want to be able the change in the settings? https://dllc.loanpaymentplugin.com/ There are already a shedload of options: All the labels Slider min, max, initial and step values Currency Interest rate Admin/processing percentage fee Slider period and repayment period (days, weeks, months. years) Output row selection Background and text colours What's missing?
