Sharing your screen shouldn't be this hard. On an ultrawide, sharing the whole display makes everything tiny; sharing a window means rearranging your work. UltraWin lets you drag-select a region and share just that.
- An invisible second display — the selected region is mirrored to a virtual monitor your meeting app can share. Nothing new appears on your screen.
- Lives in your menu bar — always at hand, one click away. Or press
⇧⌘Ufrom any app. - Move and resize while sharing — drag the frame's edges and corners live; everything outside it is dimmed on your own screen.
