KaKeKiKoKu Studio 1.3: a sharper editor

An update centered on the editor and the small details that change a working day.

In the previous post I said that the next planned step was KaKeKiKoKu Studio 1.3 on Linux.

That part is true, and it is not late. KaKeKiKoKu Studio 1.3 for Linux is finished. The Snap package builds, the smoke tests pass, the integration with the AI clients works. What is left is the Snap Store side — registering, uploading, validating. I will write a separate note when that step is done.

What ships today, on the Microsoft Store, is KaKeKiKoKu Studio 1.3 for Windows.

It is the kind of release I find satisfying to write about even when there are no fireworks. It does not introduce a new shape for the product. It does not chase a feature list. It takes the place where you spend most of your time inside Studio — the editor — and works on it patiently, so that more of the small frictions stop being there.

What changed

The editor in 1.3 feels different in a way that is hard to capture in one bullet, because it lives in dozens of small details. The biggest one is drag-and-drop. Sections and subsections can now be moved with precise insertion zones between every pair and at the start and end of the document, with no blind spots. Dragging across levels promotes a subsection into a section or demotes a section into a subsection. The whole gesture finally feels like the rest of a modern interface.

Around that change there are many smaller ones that, together, change the texture of the editor. Section colors stay stable when you reorder, instead of repainting and giving the false impression that everything moved. The section header no longer collapses when you click it; the toggle moved to a small chevron on the left, leaving the header for dragging. A new compact button adds subsections directly from the header, without scrolling to the bottom. The paste menu has been cleaned up: only one entry point, the context menu, and now also available on resources that have only a description. The context menu no longer overflows the editor when it appears near a corner.

Some of these sound technical, but they all share the same purpose: when you work inside Studio for a long session, the interface should disappear. You should not be negotiating with it.

The folder dialog also got a long-overdue fix. Browse folder now behaves like any system dialog: a single click selects, a double click enters.

There is also a quieter improvement worth mentioning. Section names that are not valid — for example, names starting with a digit — are now rejected on creation or rename. If you have any inherited from earlier versions, sync corrects them automatically and propagates the change to every reference. The kind of cleanup that should never be visible to you, but that keeps the knowledge graph consistent.

The release notes in the Store mention all of this in compact form. Here I wanted to say what it is for.

Linux is next

As I wrote above: KaKeKiKoKu Studio 1.3 for Linux is finished. What is left is the Snap Store side. That will come in the next days, as a separate publication and a short follow-up here.

After that, the next areas are starting to take shape. Studio keeps moving toward the kind of work I think it deserves: not feature pyrotechnics, but a careful, honest tool for people who already live with AI in their projects.

For now, this is enough: 1.3 is out, the editor is more comfortable, and Linux is not a promise — it is the next step, already built, waiting for its public door.
