Lasso

Lasso is a window manager that lets you move and resize windows by clicking and dragging across a grid. You can also hold modifier keys to move or resize the window under your cursor.

You can create and save custom window layouts, then assign a separate global keyboard shortcut to each layout. Layouts can be exported and imported for backup or sharing. Ready-made layouts and shortcuts based on other window managers are also available to download and import.

Lasso supports multiple displays and can move windows between monitors. Its interface is customizable, and preferences can sync across devices through iCloud.
