When using the Responsive View Mode, you're usually looking at multiple devices at once. Sizzy offers several Align modes to help you organize your workspace.
You can find the Align mode button towards the left of the app toolbar.
Here's a list of align modes and what they do.
Aligns the devices in a basic, left to right, top to bottom layout.
Centers all devices.
Arranges all devices from left to right.
Arranges devices from top to bottom.
This mode lets you drag & drop devices wherever you want in the workspace and set individual or global zoom levels. You can even let the devices overlap. To learn more, see Float Mode.
In addition to using the toolbar, you can switch between align modes by using Butler. To invoke Butler, press Ctrl+Shift+P on Windows/Linux, or Cmd+Shift+P on macOS.
In the search bar that pops up, write align to see all available align modes.
