I actually like it this way. The amount of times i would accidently favourite something.
I agree (poor placement I believe to be the problem), and I have several that have been turned on by mistake.
Since the update however, no you can't turn them on, BUT YOU CAN'T TURN THEM OFF EITHER. So now I am stuck with a bunch of favourites, that I didn't want on and now can't turn off.
And yes I am feeling very frustrated with the game, especially today (see the thread I created a few minutes go, if you want to know why)
