The oil light on a car is also small .... but at least its there and you have to get used to checking for it.  Ripple Edit is easier to miss
 

There is a another serious long-standaing problem with Offset Mode. When you have used it on a track and then switched back to normal mode, there is that there is nothing to indicate that it has been applied. You need to make a note of it, otherwise you are likely to forget about it. I've got a bad memory so it's no good to me.

Yeah that always seemed like a pretty bad miss to me. Only ever used it the once until I discovered that when moving frozen synth clips in instrument tracks it didn't also move the underlying midi, so unfreeze a few synths for tweakage and suddenly you're all over the place. That was enough for me to pretend it didn't exist and carry on the way I always had.
 
The one that will always annoy me most is that they somehow broke the undo function and never fixed it. Hard to believe that was a difficult fix, but it just got ignored.
