I work on a [34-inch ultrawide / 49-inch monitor] and kept losing time dragging windows around. Every window manager I tried was built around halves on a laptop. On a wide screen you want thirds, a centre column right in front of you, and a quick way to get the whole desk back after a restart or a meeting.
So I built Kumiko. Snapping and layouts adjust to the screen's shape, and Resume reopens your browser tabs, editor projects and terminal folders. You can also type what you're about to do ("review PR 482 and reply to the team") and it picks and arranges the right windows. The AI is optional: you can use Claude, your own API key, Apple's on-device model, or nothing.
Feedback that would help most:
Ultrawide and 32:9 users: do the default thirds and the centre column match how you actually work? What layout is missing?
The command bar: did a plan put the wrong window in the wrong place? Tell me what you typed and I'll fix it.
Resume: which app didn't come back the way you left it?
Price: it's €30 once for 2 Macs (€9 at launch). Would a free trial change whether you'd try it?
Congrats on the launch! Resume bringing back the whole desk after a restart is the part I'd use most, since I juggle several displays. Nice that the AI is optional and can run on Apple's on-device model. Does Resume restore windows to the right display when a monitor is unplugged and plugged back in?
Resume is the part that got me — I restart my Mac more than I'd like to admit, and rebuilding the whole desk (editor, terminal, browser) every morning is the most annoying part of the day. Curious how it handles apps that work as a pair, like an editor and its terminal folder — do they come back as one layout, or do you place them separately? And yes, a short trial would make me try it — window managers are so workflow-specific that I never trust screenshots alone. Congrats on the launch!
