Due to replaying the game often with different characters, I tend not to hit whatever is the cap for gold only containing chests to have their animation be skipped.
That makes so leaving a character grinding eventually have it halted because some boss dies near my character and triggers the chest open prompt.
My suggestion is that if the chest only contains gold, and the character didn't moved for a in-game minute or two, the chest animation is skipped, and give instead the gold reward directly.
Maybe would make it a lot more interesting to only begin to trigger that after owning the Yellow Sign, since it also has an effect on chests.
