“Window manager” covers tools that switch, search, move, resize, dim, save layouts, or group windows by project. A long feature list is less useful than identifying the exact failure in your current workflow.
Name the task that fails
Decide whether you cannot find a window, distinguish same-app windows, keep a useful layout, return to a project set, or reduce visual distraction. Record the number of apps, same-app windows, displays, and Spaces involved. Test Command-Tab, the app’s Window menu, Mission Control, App Exposé, and built-in tiling first.
Match one capability to the failure
Choose a window switcher for direct selection and previews; a tiling tool for repeatable sizes and positions; a layout tool for restoring geometry; a launcher for opening files and URLs; and a project organizer for returning to existing cross-app windows by outcome. These categories can overlap, so verify the exact object and recovery behavior.
Test permissions and edge cases
Use real windows with duplicate titles, minimized state, full screen, multiple displays, and a closed/reopened window. Check keyboard conflicts and whether the app needs Accessibility to control windows or Screen Recording to display previews. Read the product’s current privacy statement rather than inferring storage from the permission name.
Wallo is aimed at goals, to-dos, and existing project windows. It is not an automatic tiler, session restorer, tab manager, or app launcher. Choose it only when that organization model matches the verified gap.
