I have a lot of classes that are assigned to multiple groups.
There are 2 problems with multiple groups:
1) The index at the left (html) always opens in the groups, not in the classes tree.
Can I use the groups without a group index at the left navigation panel?
2) The group that is opened seems to be rather random - it is not always the first goup and not the last group the class belongs to. (How) Can I determine the group that is opened in the navigation tree when I open a class?
