Hey Evadne,
The text shrinking was actually requested by 20 different beta testers, even though I initially hated the idea, and am looking at ways of improving it.
The UIActionSheet should come from the bottom, it's a bug I need to fix (that randomly came about as I deployed)
I accept the point on comments, I'm currently redesigning them for the next version.
As for readability/social etc, it's a useful feature, so why not include it as a bonus?
