Seems very good. I like it more now than the last time I've seen it published here.

But with tons of alternative frameworks available, all inspired by React (including all the varied ways of structuring a React application), the problem that bugs me is that of the availability of libraries/components, like drag-and-drop things, comboboxes and so on.

Used this in three apps and I am a fan of this anti-bloat approach that enforces a few important conventions (single state updated through actions) but allows great flexibility otherwise.

I used it a bit and it's awesome. The fact that it's small is not only nice from a anti-bloat perspective, but I've also found that just being able to read the entire code in a short time really helps understanding how it works and how to best use it.
