Suggestion: Drop unnecessary confirmations.

[SamSmoot]

Try to open a door that leads to an instanced area, and you get asked if you want to open it. This is annoying.
If it takes less then 30 seconds to reverse an unintended door transition, and it costs nothing, then there's no need to ask for confirmation.
We waste more time clicking these things than we would by accidentally clicking them occasionally.

[Rongway]

If a door or transporter is inaccessible until the area is safe, then there's no reason to require it to be clicked at all. Just open the door or activate the teleport pad as soon as the trigger mobs are dead (and, if necessary, draw a zone line through or around it) and automatically transport anyone who steps into it.

"aRe yOu sUrE yOu wAnT tO hAnD iN a hIgH quAliTy iTeM"? I don't use plugins but I will say that YesAlready seems really appealing exactly because of this. There are so many stupid confirmation windows that pop up for EVERYTHING. Just let me toggle them off in the settings, please, I beg you, SE.
