Doorway studies examine how physical event boundaries can affect recall. This article considers that research as a design analogy for digital work, not proof that every app switch causes the same effect.

A review of Ikuna in 2026: saving project apps, browser tabs and window layouts as workspaces, plus the distinction between current features and future plans.

I get it. At first glance, Ikuna looks like a window manager.

That's not an accident. We put the snapping and the layout on the surface deliberately, because in 2020 that was the fastest way to explain what the app did in ten seconds. If you're evaluating productivity tools and you see windows snap into place, you understand the value proposition immediately. Rectangle does that. Magnet does that. Stage Manager does that. The category is legible, the benefit is instant, and you can decide whether you want it in about thirty seconds.
