Since #191 (comment), should we enable GUTENBERG_EDITOR_URL by default? I keep doing this every time I work on the editor.

Sounds good to me. However, let's also enable the GUTENBERG_EDITOR_REMOTE_URL environment variable as well.

We should also update the README documentation to match the new default settings. The README recently changed. I suggest rebasing this atop the latest trunk branch and applying the following diff

Enabled, and I updated the README as well.

I don't feel strongly about it, but ToolbarButton needed some design. I don't think it needs to stand out as much as it currently does (a single black spot on the entire screen).

I think this is fine for now. Eventually, we need to consideration Android design patterns.

Only passing the information we need to show the editor (except for the icons – we'll need to figure out how to manage those).

Looks like a solid start. I left a few suggestions, but approving because this worked as expected for me.

I suggest retaining "bundled" somewhere to differentiate from the remote editors and remain aligned with Android's demo app/project documentation.

Sounds good; done.

+					setIsInserterOpened( false );

Is this achieving a specific outcome?

It hides the previously selected sheet. The web-based inserter does the same thing, so I implemented it for the new inserter as well.

<Inserter popoverProps={ { 'aria-modal': true, role: 'dialog', } } open={ isInserterOpened } onToggle={ setIsInserterOpened } />

I suggest we place this after the attributes declared for .gutenberg-kit-editor-toolbar .gutenberg-kit-add-block-button. I.e., move this after the current line 88.

+import { getBlockTypes } from '@wordpress/blocks';


While rebasing #197, I discovered this import is problematic for the "remote" editor, which currently fails to load. The import results in a reference to window.wp.blocks before this global is defined by scripts loaded from the remote site.

I'll create a PR addressing this, likely by splitting (or "chunking") this bridge method from the rest.
