[Pharo-project] Something I don't understand with Method Finder

Hi folks! If you look for example "gently" in Method Finder, you will see that it lists, for example, "enableGently:" and "disableGently:" However, those methods are not implemented, there are no senders, and I even did a "method source with it " and I found nothing. In my final shut, I read the .changes and I found: "Preferences class removeSelector: #enableGently:!" Now I wonder...is this a feature of Method Finder to look also in .changes or it is a bug ? Anyway, it is not clear when you find a message but you don't have implementros or senders, it means that it was in .changes. What do you think? Thanks Mariano
