I agree, as much as I like the hints it lends itself to the weird situation where you keep wondering "what if i succeeded in this check" so you basically save-scum to find out. This left a bit of a sour aftertaste for me - in a DnD campaign the GM can turn failed skill-checks more interesting - here it's more like "bleh, but i really wanted to do that - time to reload".
IMHO a nice way would be to have an option that hides all skill-checks as well as a "special" option that lets you pass all dialogue-triggered skill-checks (maybe after you have completed the game once).
