ShiftIt

ShiftIt provides fully customizable hotkeys for resizing and repositioning windows, allowing users to tailor the tool to their workflow without mouse intervention, as highlighted in its feature list.

It supports snapping windows to halves, thirds, or full screen edges, enabling organized layouts that optimize screen real estate for multitasking, as described in the key features.

With optional size cycling, users can cycle through multiple window sizes (e.g., half, one-third, two-thirds) by repeatedly pressing shortcuts, adding versatility to window management, per the FAQ explanation.

ShiftIt runs from the menu bar with an option to be completely hidden, offering a discreet yet accessible interface that doesn't clutter the desktop, as noted in the installation guide.
