For hourly employees, sometimes there is no clear, simple way to keep track of your own times for the week. Many people, myself included, need to make sure their next paycheck will cover their expenses. Keeping track of weekly hours, adding them up, factoring in hourly pay, and then removing the correct amount for taxes is time-consuming and stressful.
Instead of using default hourly pay and withholding rates, I made it optional and added settings to change this as needed. When a period or comma is typed, it is replaced with a colon, so typing in the times is much easier. This also helps with typos when validating the inputs. I added a feature to remove time entries in the event of mistakes or for those who estimate and "budget" out their time for the week.
