I have 2 problems:

1 In "My Page" view, sub project and its parent project shows in the same level, so I have to give a full name for the sub project, because it has lost its context here.
2 In "Issues" view, if a project have multiple sub project, some sub projects show in the same level as its parent project, while some not, and what is more confusing, for example, if I changed something in the sub project, say New -> Resolved, the level changes, say parent level -> child level.

Is it by design or a bug?
