Gutenberg's "Image" block must be used, because it's the only way to add images to content. it should however, be adjusted to render images exactly like the current P4 "Add media" feature.

TASKS:

• Disable "Inline image" command (see snapshot)
• Enforce default caption style as the P4 blue overlay, not the white "MEDIUM Style" one as it is right now (see Snapshots)
• Add styling for MEDIUM style Caption (no overlay) on the right-side commands
• Add text alignment commands for caption (Left-Center-Right) - default as right alignment
• Add sizes to Styles of image (Thumbnail - medium - Full) on the right-side commands, like the classic P4 commands (see Snapshots)
