Window management

Move and resize the window you were last in, without installing anything else.

It needs no new permission. It reuses the same Accessibility grant that clipboard pasting already uses.

Settings → Window Management holds the feature switch. It ships off; while off there are no launcher entries and a still-registered shortcut moves nothing.

The commands

Halves — Left · Right · Top · Bottom

Quarters — Top Left · Top Right · Bottom Left · Bottom Right

Fourths — First Three Fourths · Last Three Fourths

Thirds — First Third · Center Third · Last Third · First Two Thirds · Last Two Thirds

Sizing — Maximize · Almost Maximize · Reasonable Size · Maximize Height · Maximize Width · Center · Center Half · Make Larger · Make Smaller · Restore

Moving — Left · Right · Up · Down · Next Display · Previous Display

Fullscreen — Toggle Fullscreen

Spaces — Switch to Previous Space · Switch to Next Space

Settings

Per-command shortcut and visibility live in this same pane — window commands deliberately get no launcher pane of their own.

Clearing a recorded shortcut is how you disable one. There is no separate per-command switch.

Geometry

Gaps. An edge on the screen boundary takes the full gap; an interior edge takes half. So two adjacent tiles leave exactly gap between them and every screen edge is inset by gap. Rects round on their edges, so thirds never overlap or leave a one-point seam.

Make Larger / Make Smaller step by 5% of the screen, not the window, forced so each edge moves a whole point — which makes the two exactly invertible. The ceiling is the screen; the floor is 200×150 or 15% of the screen, whichever is larger. Both saturate into clean no-ops.

Reasonable Size is 60% of the screen, centred, capped at 1025×900 points — so a 5K display gets a sensible window rather than an enormous one. It ignores the current size, making it idempotent.

Center Half is half the screen's area: half width, full height, centred.

Oversized or off-screen windows are always clamped back onto the display, pinning the leading edge. The usable area already excludes the menu bar, the Dock and the notch.

Cycling and Restore

Cycling covers the four halves only, stepping ½ → ⅓ → ⅔, and is off by default. Top and Bottom Half cycle through vertical thirds.

It restarts at ½ when you move the window yourself (more than 2 pt), on a different command, on a different display, after a timeout, or when cycling is off.

Restore is single-level, not a stack. Left Half → Maximize → Top Right → Restore lands on the original frame, not the previous one.

Restore also works on windows Tinycast has never moved, because the frame is captured before the first change. Memory is per window, capped at 64, dropped when the app quits, and never written to disk.

Fullscreen

Toggle Fullscreen uses the accessibility fullscreen attribute, falling back to pressing the window's fullscreen button, then to a quiet no-op.

There is deliberately no synthetic ⌃⌘F attempt — apps can rebind it, and firing an unrelated menu command would be worse than doing nothing.

It clears the cycle chain but keeps the restore point.

Spaces

Switch to Previous Space and Switch to Next Space move between macOS Spaces without the sliding transition — roughly 56 ms, against about a second for the system's own ⌃← and ⌃→.

They work by synthesising the trackpad swipe macOS already switches Spaces with, at a velocity high enough that the transition finishes rather than animates. Desktop Spaces and fullscreen Spaces are both included, since it is the same gesture either way.

Held down, presses that arrive while a switch is still in flight are dropped rather than queued, so a long press never overshoots. At the first or last Space, macOS does whatever it normally does.

Failing quietly

Windows that are minimized, sheets or popovers, already natively fullscreen, or that report no position or size are rejected before anything is attempted.

A non-resizable window — System Information, for instance — is left alone rather than half-moved. If an app refuses to shrink, the window is re-placed against its anchor once, never in a loop.
