Here's another vote for fixing the suppression thing, that's always bugged me because I have to manually calculate the caps. Given that the unsuppressed defense on something like Hide or Stealth is only active when you're not in combat (and thus, mostly useless) I'd be perfectly happy if you just defaulted to the suppressed numbers on those powers, and skip the UI changes.
Found an odd bug in the branching for Frag Grenade on my Crab Spider. Frag Grenade (Wolf) and Frag Grenade (Crab) are supposed to be mutually exclusive. Instead, the Crab version is greyed by default, and becomes available after you take the Wolf version. If you try to take both, it tells you that the Wolf version is placed invalidly, but the Crab version is fine.
Edited:
Ninja Run is also behaving weirdly. On some toons it's telling me that it's placed illegally, and on one toon it was hidden. I could hover over and click it, but nothing was displaying. Seems to only be messed up on old toons, though, so might just be a weird thing in old files.
