Another is the *lack* of a place to *type* a file name when you click a file upload button. The file upload browser both comes up too tall (taller than my screen [why?]) and lacks a place to start typing a file name, one *must* scroll down though (in my case) a long list of files and directories. It seems that the use of a keyboard is no longer supported. *Some* of us actually use our keyboards and don't like to point and click *all of the time* (or really much of the time or really at all). I know, the keyboard is a piece of depreciated hardware -- we are all supposed to be using touch screens with only colorful icons -- actually typing file names is so 20th century... :-)
My experience, although it may depend on versions etc., is that if you just start typing in the file upload browser, the search bar appears and the list of "available" files narrows down until you get what you want.
