1. The auto-use item feature by fairy takes a little long to use the potions ( like 10 seconds long). That decreases the efficiency and damage I do to monster while they reuse the potions.

2. Make the auto-use item feature stay on even after death or log out. I sometimes forgot to turn it on and my damage decreases.

3. Make the item count stay visible even after depleting trash loot or log out. The item count always disappear when i put trash loot into my storage and when i log out. It cost me like 30s ( a nuisance) to turn it on again.

Mate, if your time is wound so tight that something which takes less than 30 seconds to do is too much of a nuisance or inconvenience, you might need to rethink your life. 

As for auto use, better that it turns off automatically and you have to turn it back on, than that it stays on through death/logout and waste stuff when you log in. 

1. That is because the elixirs themselves have cooldowns. The fairy cant use them when they are on CD.

2. After death, yes that would be nice. After logout, I'd rather not, just in case you log out with it active and dont want to waste the buffs.

3. Agreed with that one, that would be nice QoL
