Whatever is written in 'Short Name' is used in 'Show/Hide Items'
Currently, whatever is written in the 'Your Replacement' box is what is used in 'Show/Hide Items'.
I have customized almost every entry. Often I will put a long description in the 'Your replacement' box, which makes identifying and item to toggle on/off difficult. As well, when you make a bunch of these long entries under one subheading, they can't fit inside the fixed size of the window ( on screen) and they bleed way out to the right. You have to go all the way to the bottom of the page to scroll over to see what is hiding off to the side.
Enabling 'short name' to determine the item name in the 'show hide items' list would eliminate this problem as well.
If nothing is entered in 'short name' the software could default to whatever is written in 'your replacement'.
