Not a bad idea, but I'd like to see the current functionality remain for those of us who are already familiar - and the new functionality added on top. As long as that's fine, this may be really helpful.

Which things would it do, and are any of those spoilers?

Open/Close Door
Handle lever
Sip pool
Pray at altar
Use forge?
Pick up items?

What about statues - since there are multiple possible interactions you might want.
Or beehives.

Some of these are things you might want to figure out on your own (not the open door/handle lever stuff). If you get used to one command doing everything, you either remove people learning about these things, or imply that there isn't anything to do, even though there is.

Absolutely. I'm currently not thinking about removing any old commands. We just need simpler new commands for new players. And I am pretty optimistic.

(a) ADOM will avoid spoilers by analyzing what the player perceives and only offering commands that should be obvious if you read the manual.

(b) You still have to prioritize your actions (as usually there are many options available to you). So the game still is far from trivial but only offers a list of reasonable commands without forcing you to learn each command sequence.

Nice idea. That's a beautiful way to reveal functionality.

I had been contemplating how the numerous key-presses of ADOM, and how a new player would ever learn them. This will take care of that well.

That does avoid spoilers, but are there any commands that won't appear on the list that players will assume will never work simply because they don't appear on the list? Rarely a player wants a seemingly unreasonable command. Maybe if the pop-up said "Common commands" or something as a header? So it's clear it might not be *everything*.

Implemented.
