Well, it's not entirely new. It's been available for a few weeks, and it's actually a revamped version of an older module I used to offer, SWADE Wounds Calculator.
SWADE Targeted Damage (STD? Really?!) allows you to resolve damage against targeted Tokens rather than selected Tokens. The module sends a prompt to the Token's owner to step through the flow of adjusting and resolving the damage, calculating Wounds, Soaking Wounds, rerolling Soak attempts, etc. It's simply an alternative for resolving damage if using targeted Tokens feels more intuitive to you.
(I have not tested this with SWADE Tools or Better Rolls 2 for SWADE.)
