Sometimes, when a user has caused a significant amount of "damage" to the protein during a large change, the score drops to zero. In fact, one can cause so much temporary damage that the score is well below zero, although undisplayed

I would like to suggest the addition of a clash score to note how large the magnitude of the clash is, in much the same way a player can now calculate clash strengths based on the difference between a model's resting state and the clashed situation, just that it would display the results of that calculation for the player, specifically for those instances where the score drop to/below zero. This would be useful is seeing just how much work one has to do and one's progress when manually rebuilding or otherwise performing major surgery.

The score could be incorporated into the present score box. I would place it, in a slightly smaller font, below the score, and I would use red for the text color to indicate it's negative impact, much like "battle damage" displays in many other games.

The attached picture shows what I mean

thank you
