Every time you Command-Tab, your brain treats it as walking through a door. The literature on the doorway effect says that crossing an event boundary flushes some of the state you were holding a second earlier. On a modern Mac, you cross fifty of those boundaries a day. That's not a productivity metaphor. It's a specific finding about how the brain segments time.

A sensory anchor is a repeatable sensory input, whether a sound, an image, a smell, or a place, that becomes associated with a cognitive state through repetition. The next time the input appears, the state loads faster and cleaner than it would from a cold start.

I ramped production back up after a long stretch of keeping the lights on but not much else. Seven months later, Ikuna is stable, the intelligence layer is in, and the product is finally what it was supposed to be from the start. Not a window manager with extras. A focus intelligence platform that happens to use save and restore as the mechanism.

This is the narrative changelog. Not a bullet list, not a press release. The honest version of what shipped, what we got wrong, what's coming, and where the company is actually aiming.

When I went fully remote, my productivity didn't dip. It collapsed.

It wasn't dramatic on day one. I had a laptop, a kitchen table, a reasonable internet connection, and what I believed was a decade of self-discipline. By month two, I was finishing the day with the same feeling you get after a long flight: I'd been on, technically, for nine hours and could not point to a single block of real work. Meetings ran into deep work, deep work ran into messages, messages ran into a half-written doc I'd already opened twice that morning. Each evening I'd close the laptop convinced I'd just had a bad day.

Yes. Having too many windows open on your Mac actively degrades your focus and productivity, and the mechanism is more insidious than you think.

Those windows stacked behind your active document aren't neutral. They're not just sitting there waiting patiently. Princeton neuroscientists discovered that multiple visual stimuli in your field of view compete for neural representation by mutually suppressing each other's activity throughout your visual cortex.

You didn't work late. You didn't pull an all-nighter. You didn't even have a particularly stressful week. Yet by Friday afternoon, you're mentally spent, unable to focus, irritable, and counting the hours until you can close your laptop. The exhaustion doesn't match the workload.
