This is somewhat related to ZombieMan's post, but I thought I'd go for a new topic anyway. As of the May 20th redesign, I believe it is impossible to access pets, accolades, inherents, temp powers--anything that isn't a powerset or pool power.
The most obvious obstacle is that they're simply not linked to; the City of Data homepage only has links to the major archetypes.
Even if you are able to access the old drop-downs (which you can, but selecting a specific power--the drop-down will be there), selecting anything other than an archetype primary or secondary simply takes you back to the CoD homepage.
Needless to say, that's a lot of information that's lost to us.
