All the information is there you're just asking for it to be easier for you to find. Once you start down that road its a slippery slope.
A slippery slope to what? A game with a better interface?
How easy it is to find information makes a huge difference when you are playing a game. How much do you know about any random dwarf in your fort? Do you even see them as distinguishable at all?
How do you know when a dwarf is injured, or when a dwarf is unhappy, but not unhappy enough to actually cause a tantrum or the down arrow indicator to pop up on the screen as, again, a visual indicator of information on the play area window?
Unless you are religiously tracking all the detailed views of your dwarves on a game-daily basis, or are using Dwarf Therapist to give you more information more easily, then you aren't getting that information at all. And most people just skip that part if they aren't using Dwarf Therapist.
The same goes for injuries - you basically can't tell a dwarf is injured if there isn't a mortal wound indicator or a blood trail or you are looking at their information page for some reason. Without that reason to look, why would you ever notice that injury? Unless there is somehow an indicator that attracts player attention to the fact that there is a problem, why would a player ever go looking for information they may need?
There were plenty of problems with a "bug" in DF where people had doctors that refused to treat patients, and nobody understood why. The reason why was because the doctors had a personality trait that made them not want to help others, so they refused to do it,
but that information was never conveyed to the players, so they never figured it out, and just figured the game must be buggy.
Mechanics in a game are useless unless the game somehow can transmit the effect they are having in the game as information to the player. If the interface is so convoluted that players don't even know where to look for the information on their problem, or that they don't even realize there is a problem at all because that information was never transmitted to them, then it is the failure of the game, not the player.
