I swear there used to be more menus at the top of the forums on a non-mobile browser. One could quickly search for subscribed threads, for example. I no longer see these menus, were they (re)moved?

 

Ya, it changed for me and changed for the worse also imo about 2 months ago

 

In the upper right hand corner of the screen there is dropdown menu below your username, most of the "missing" items are located there (some others can be found in the various dropdowns located in the top tool bar).

FWIW, I liked the old arrangement better too; not sure what the reason was for the change.
