It was, in my opinion, a cool idea to add Trapfinding in the Shadow Dancer Epic Destiny but somehow it was removed after preview 2 or 3 on Lamannia and it didn't make it to U51.
So I ask if you maybe can bring that back because it fits thematically perfectly to SD (in my opinion) much better than giving the Magical Training feat which is provided by so many EDs in Core 1 (a bit boring).
One way could be that Core 1 provides once again Trap Finding and the Magical Training feat is instead provided with rank 3 in Well of Darkness.
Another thing is I would like that the Watchful Eye Feat also provides the ability to autodetect hidden doors (if you have the search and spot for it) and the tooltip should tell you that you not only need the search skill in order to make it work, you also need enough spot to detect the trap.
