Trying to align objects on the screen but no grids or auto-snapping to help you out? Just call up Crosslines with the push of hotkeys. It's that simple. Move around crosslines to help determine alignment.
The crosslines will show on the screen (multiple monitors supported) no matter what kind of app you're running. The crosslines is a system-wide feature that makes it compatible with virtually all other apps.
