Close all files / tabs
Add "Close all files" option to Files menu, with keyboard shortcut; add "Close all tabs" option to tabs' right-click context menu.

Agreed. Since Ctrl-W is Close File, maybe something like Alt-Ctrl-W to close all open files. Leaving Reader itself open.
to add to the above, should emphasize that there should be an option to close all tabs but Adobe Reader itself stays open
