I love the new settings to turn off the "death handling"! But it seems you "missed" adding an option for moving the token from the top layer to the middle layer on death, which is still a giveaway that it's died, even if it's not immediately obvious as with the visual elements.
I'd also like to know if you looked into allowing capping the damage against an NPC so there is 1 hp left? I'd really like to be able to have the "death effects" but still be able to not instantly reveal that someone died. But for all I know this could be impossible to do in FG if you for instance can't intercept the damage event in some way or similar.
If you have not looked into it yet I may look into making a separate extension myself that does just this (if it's not impossible to do).
