Snap windows with ⌃⌥ and the arrow keys, pick one of six layouts that fit your screen, or just say what you are working on and Kumiko arranges every window. Kumiko is a macOS window manager made for ultrawide (21:9, 32:9) and big 4K/5K monitors. It is made by Jahvix (https://jahvix.com) in Ireland. It needs macOS 14 or later. Key facts: - Price: €30 one-time licence for 2 Macs, no subscription required. Launch pricing: first 25 licences €9, next 25 €18, then €30. - Optional Kumiko AI add-on: €4/month or €36/year (Claude via Kumiko's server).
