Pros and cons

What you gain

One rule. If you know the layer, you know the folder. domain/notes, application/notes, data/notes, and presentation/notes are the whole feature. A new port has one obvious home.

Diffing this tree against hybrid is mostly the screen path. The use case file is the same class in a predictable place.

What it costs

A screen change touches the presentation layer, and a small widget has no separate presentational tree to hide in. presentation/notes/ grows the page, the notifier, and the tile together.

Cross-feature work is easy to find and easy to entangle. Two features that share a widget either lift it to presentation/shared/ or copy it.
