Sorry just adding to the list. Lume (aka luminous phosphorescent) on a few of the dials. I recall my older camera's would glow in the dark, but not this new line(s).
I've only been using my AC130 for about a month now, but here's some "upgrades" I'd like to see:
1) 1080 60p
2) Improved OIS (I started a thread on this)
3) A larger record lock release button (my fat fingers struggle with this) While you're at it, a larger record button would be nice as well.
4) Larger and/or better placed Iris Meter display - my old eyes have a hard time seeing that little bitty thing (and it gets covered up by the Focus Assist.
5) Less cumbersome Auto Focus button - maybe something akin to the Iris or White Balance buttons.
The cap is best taken off and stowed. If ever you sell the camera, buyers will figure you took good care of it if you can produce the cap. (not my invention)
