This seems inconsistent right now, but I would like to see this menu available on all the community pages, so you can quickly navigate to another section. Many times I'll be watching questions in the Teamcenter, Design, and Manufacturing sections, and it would be nice to go directly to them, without having to backup.
It could just be a Chrome thing, but I don't see this menu on all of the pages, and pages I thought I saw it on one day, don't have it the next....or my memory is just failing me.
My response on this is a bit late, but can you tell me what pages you're not seeing the menu on? I just checked a few (NX, Teamcenter, and Catchbook) and they all had the menu visible. If I can replicate the issue, we will be able to fix it. It may have been resolved already though.
