What "hotfixes" are you requesting? If you could elaborate I could add those suggestions to our to-do list, but the way you've worded this isn't exactly clear.
From my knowledge of how Minecraft works, the server never actually sends a "player is dead" packet, instead the player just kind of disappears when they die. I could be wrong about this. Either way, why would this be an important feature to add? As far as I know KillAura already works fairly efficiently, not sure if it stops immediately when a player dies, but is that really important?
I think it might be cool if we were to add another modules tab for "Automation", and code a few quality-of-life automation things into Vape for you guys to use. That would be a pretty novel idea, and your suggestion regarding auto-eat would fit perfectly there. I've added your suggestion (and my accompanying automation tab idea) to our to-do list, maybe it will get added to the client sometime soon.
Is this really necessary? We already have Tracers, Nametags, Arrows, Player ESP, Chams, the list goes on and on. I'm pretty sure (unless it is now deprecated and I haven't noticed) we even have text radar that shows a list of players in your render distance alongside how far away they are from you.
