After reading, and re-reading OP a few times, I find it difficult not to reply without sarcasm. I also read your first post. Miraculously, I can have my priest pray 3 times while I imp/build/mine/travel.
If I could queue 10 actions, i'd run out of stamina on most after 4 with skiller tools. With speed tools my skill gain would equal maybe 1-2 actions anyway. If we remove stamina to make your idea work, we break all parts of the game from swimming to climbing(those massive dirt walls around deeds on epic come to mind).
Maybe mouse batteries are costly so you don't want to click. I have a logitech that only needs a single AA battery every 3-6 months, was extremely cheap too.
Or perhaps you want to do other things while "playing"(Google Idle games or 4x games)
