No need to say sorry .It's the same for me. Hover over forum/members/help and you get a dropdown, submenu. Just like personal account box and inbox/other one.
Indicators for dropdowns, is what the icon is for in my book. Sorry that we see it differently.
a perfect explanation ...No need to say sorry .
Also in addition to my previous explanation, realize that [Forums] [Members] [Help] are part of, in fact are XenForo's sophisticated menu system. Those arrows there have a specific function. And when you realize that both Alerts and Inbox are simply not part of this clever menu system, then... the arrows are not needed. This is the other reason they are not included.
Yes.I believe that is by design. The dropdowns towards the left are supposed to be less intrusive, and people can navigate without using them.
The drop down near name does not work that way.
