Save All and Close All
Add a 'Save All' and 'Close All' to the File menu. Photoshop and other Adobe software have had this since the '90s, so why doesn't InDesign? It's inefficient to click on dozens of documents one at a time in order to save them and/or save and close them. Please emulate Photoshop as the ideal example.

Love the shortcut reminders and the script, but this seems like a fairly easy addition to the File menu, and would be "discoverable" for new users, which is always a plus.
Heres a line of code for an extendesscript: Closing all docs without saving
thats all :)
shift-ctrl-alt-S = save all open files
shitt-ctrl-alt-W = close all open files
(Whatever the Mac equivalents are probably work the same way.)
I've been doing this in InDesign for as long as I can remember.
