1. A long time ago, at my first playing round (before quitting), I asked the very same question. Confirmation screens. Was told the exact same answer you get now, simply no. I'm pretty sure there are reasons, and I can live with it. We gotta be careful and unfortunately misclicks happen. Sometimes to some grave results. But lets use that 'chance' to RP around it or anything. Nothing we can do about it.
By the way, never had that much misclicks as you. The most often it happens that I loot without setting the correct options, or losing a half finished message or those things.
2. I am open for a list of areas where the link order could be improved, like the dungeon actions you just mentioned. List them all up and we can look and review them and perhaps change something.
3. Place buttons further apart is definately on the agenda. Just need someone to take the time.
