I'll have to look into it. My current method is the weight listed on the left is added up, the weight on the right is just what the item weighs so I can easily added it. The colord items are a group that serves one purpose. For example, I have 3 stoves, but only need to take one, so stoves are grouped together and highlighted the same color.I really enjoy the formatting of The Exo Gear List especially since you can check boxes varying upon what you need for the specific trip. It also adds the weight depending on what you’ve added.
Check boxes would be simpler.
