When typing
const std::vector<int> a;
a.p
I dont't get a suggestion for push_back, because a is const.
If I remember correctly, older VA-Versions did display these "forbidden" suggestions - but I don't find any settings to bring them back.
Its unquestionably super useful to be reminded, that they are forbidden (grayed out / red warning / ... ), but it would also be useful to see the whole interface (at least if desired via settings)
