Comment 57 for bug 925895

Jordon, comment #27 clearly states that right-click menus are intended to be light, and the light sub-menus have been fixed in the meantime.

It's fine if you disagree with design decisions, but a bug report is the wrong place for discussion. Every time you post something, all subscribed users might get notified by mail, which can be quite annoying in cases like this, where the bug is fixed.

I suggest using the unity-design mailing list.
