Shed Editor Assist enhances the Gutenberg block editor experience with visual aids that make layout structure clearer.
Features:
<ul>
<li>Layout Borders — dashed outlines on Columns, Column, Group, and Spacer blocks so you can see structure at a glance</li>
<li>Block Color Coding — each block type gets a distinct border color (paragraph, heading, image, list, buttons)</li>
<li>Grab Markers — a ⠿ handle at the top-left corner of each block for quick drag-and-drop reordering</li>
<li>Backspace / Delete Protection — prevents accidental block deletion or column-merge when the cursor is at the start or end of a block (both keys protected)</li>
</ul>
All features are editor-only. Nothing is added to the frontend.
Each feature can be toggled independently under Settings > Shed Editor Assist. Border style (dashed / solid), width, and base color are also configurable.
Optional paid add-ons are available at https://wpshed.jp.

This a Gutenberg plugin that adds an outline around each block. Outline settings are based on user meta. Each user can 
change the settings according to their needs and it will applied only to their account.
Users can change:
<ul>
<li>When to show outline. On hover or always displayed.</li>
<li>Lock outline for a single block.</li>
<li>Disable outline completely.</li>
<li>Show data (name and class) outside block, inside or floating when hovering over block</li>
<li>Change outline color.</li>
<li>Change outline style to solid, dashed or dotted line</li>
<li>Change padding size</li>
<li>Show/hide block name</li>
</ul>
<h3>Filters</h3>
<ul>
<li>editor_outline_default_user_meta 
You can override the default user meta by using this filter. The filter will receive the default user meta as an array and 
you can return a modified array.

Editor Block Outline

Great work. I've been considering making a similar plugin myself, so I'm glad I found this one before I did. It works well and makes it considerably easier to see where each block is. Especially useful when you have blocks within blocks. i.e. Group -> Columns -> Column -> Paragraph

Makes Gutenberg usable

I like this.

When I edit multiple blocks, this plugin help me.

Very useful plugin
