This has sort of been rolling around in my head in a couple of the [Balance] threads, and I thought I'd put this here since it doesn't really fit in any of them. Basically, I think that there are a lot of things ingame that are kind of annoying to do because you can only do it slowly, one at a time, when there should really be a way to do multiple actions of the same type at once. In particular:

Smithing:
-Make it so that the character can refine multiple pieces of ore into ingots all in one step. Instead of having to do one piece after another, let the character select 10 iron ores, 6 mithril ores, 2 adamantium ores and 1 eternium ore, wait the total number of necessary turns, and spit out as many successful ingot retrievals as he ended up with.
-Allow the character to smith multiple ingots in a single item sequentially instead of one-at-a-time.
-I'd suggest doing something similar with mining as well, but I don't have a really good idea for that. Maybe an option to mine a given number of squares in whatever direction (or until the pickaxe breaks or a monster appears).

Herbs:
-If a herb bush is not withered, the PC will pick all herbs on the bunch until it is withered in one shot, then the bush dies on the next. This could take multiple turns or have a higher energy cost as appropriate. I'd recommend the latter choice as this would also fixes a problem that it is currently much easier to build a herb farm with low herbalism skill, since you can pick through bushes much quicker, which is a little counter-intuitive.
-Have w5 commands cancel if the PC notices a new herb generation being grown.

Casino:
-Let the player play a casino game multiple times with a single keystroke (eg. "$24 to play, how many games do you want to play?")

That's all I can think of off the top of my head, but I'm sure there's others worth mentioning. I'll add more as I think of them.
