Canvas — scroll to pan · pinch or ⌘+scroll to zoom · space+drag to pan · drop images/videos anywhere
Windows — drag title bar to move · corner to resize · double-click a tool's title to rename it · the small colored ring cycles groups · the expand button fills the screen
Groups — drag one window onto another and hold to link them · drag the colored label to carry the whole group · the squares button in the dock arranges group view
Shortcuts — ⌘Z undo · ⌘N sticky note · ⌘T open website · ⌘+/⌘− zoom · ⌘0 100% · ⌘1 fit all
Personalize — the dock button cycles dock styles · the pointer button picks a cursor (dice = a new random emoji every click) · speaker mutes UI sounds · moon toggles dark/light
Demo — this page resets on refresh; the Mac app remembers everything, logins included.
You rearranged things while in group view. Save keeps this arrangement as your canvas layout. Discard puts everything back where it was before group view.
Everything goes back to how it looked when you arrived. (In the real app your canvas is yours — it's saved automatically and never resets.)
Deskspace is an infinite desktop canvas — it really wants a mouse, a trackpad and some room. Come back on your Mac, or wander in anyway.
