Hi krass,

For that one area I used Rhino to help identify it using Explode followed by SelBadObjects.

For the squashed down ones, I used a process in MoI of using Edit > Separate to break the object into individual surfaces, then I clicked on every surface that I could see and after all are selected I then used Edit > Hide to hide those to reveal what was left over. Then it's a process of joining pieces back together without the tiny fragments and looking for naked edges, that can then reveal a few more problem areas that needed to be untrimmed and retrimmed.

Not currently, it is something that I want to add in the future though.
