Q: What does the blue d, red P or Exclamation Mark ! in a Yellow Circle mean?

A: The blue d means that the skill is defaulting from another skill, either at the default level or being bought up from the default.

The red P means the trait is missing a Prerequisite. You can see which prerequisites are missing by right clicking on the trait and selecting Needs or by selecting the appropriate Needs from the top menu.

The Exclamation Mark ! in a Yellow Circle Means that the trait is currently failing a taboo check - that is, you have two possibly mutually exclusive traits loaded on the character or the racial template/meta-trait normally doesn't allow a particular trait on the character. An example of this might be a character that has both Blindness and Acute Vision. Note that sometimes mutually exclusive traits are perfectly fine to have together, such as a character that has Mitigated Blindness with Bionic Eyes which also provide Acute Vision. The taboo check is just a warning, not an automatic prohibition against taking mutually exclusive traits. This warning has no effect other than to alert the user of a possible conflict - feel free to ignore this warning if you wish.
