TrellisWM

Docks, nests and tabs your Mac windows together

MacFree to start

The verdict

Instead of snapping windows to fixed halves and quarters, TrellisWM docks your real Mac windows inside each other, as deep as you like, and lets you pinch to zoom out over the whole desktop. Drag a window to an edge to dock it, drop it on another window to stack them as tabs, and save a layout to a shortcut. The free version covers 5 docked windows per display, and Pro removes the limit.
