The save button when inputting credit card transactions stays put at the bottom of the screen. When you have a credit card statement that is over 150+ line items, and wish to save, you need to travel to the bottom of the page, save, then scroll back up and find where you left off so you don't lose anything.
By having the save button follow you through the bottom of the screen, until you do reach the bottom you are able to save easier and more continually to not lose your work.
