File (first ribbon tab) or Alt+F opens a full-window view in place of the
ribbon, slides and status bar: a side menu (Back, Home, New, Open, Info,
Save, Save As, Print, Export, Close; Account and Options at the bottom)
and the chosen page. Esc or Back returns; Up/Down walk the side menu and
show each page as it gets the focus; Enter runs Save/Close/Options.
Laid out after PowerPoint for Windows as observed: 160-pt menu a step
darker than the page, outline icons, current page in the accent colour.
The start screen is now File › Home (as in PowerPoint), with only Home,
New and Open at the top and no Back. Pages call existing commands and
file helpers: file.new {theme} and the sample deck (Home, New); recent
files with search, Browse and Recover Unsaved (Open); file.info and
file.properties, Accessibility Checker, Revert (Info); file.save /
file.saveAs / file.export by type (Save, Save As); a PDF with the Print
page's slides, layout (full page, notes, handouts 1-9), hidden slides and
frames, opened in the system viewer or downloaded on the web, with a
page preview (Print, Ctrl+P); Create PDF, Create Handouts and Change File
Type (Export); appearance and About (Account); Preferences (Options).
Share (cloud) is left out.
Close and Ctrl+W now ask Save / Don't Save / Cancel about unsaved
changes instead of closing at once. The Export dialog shares
SlideApp::export_as with the Export page. New UI commands: app.backstage
{page}, app.closePresentation, app.print; ui.inspect reports the page.
New icons drawn in code: back, save as, account, recent, new file, open
folder.
