Suggestion: Mermaid / Diagrams - Preview mode

Lettera Version: Version 1.0.0 (4266)

macOS Version: 27 beta 9

Thank you for implementing diagrams! This is my go-to tool now to keep AI-generated logics easily understandable and reviewable. I would like to ask for an ability to focus on diagrams with some special view mode.

What were you doing:
Reviewing large, complex diagrams created with Mermaid.

What feature did you use:
Mermaid diagram implementation.

What happened:
Currently, there is no efficient way to view large diagrams. Neither the built-in zoom nor system zoom provide enough clarity to read complex diagrams easily.

What did you expect to happen:
I would like a shortcut+click (e.g., Opt+Tap on picture, or having a hover lens to activate the feature) to open a dedicated preview pane for diagrams that supports zooming and panning via touchpad, allowing for a much clearer review of detailed Mermaid diagrams and possibly some other formats (pictures?).

Best Regards,

Yes, we agree that we need a preview mode for Mermaid and we’re internally discussing how to add it :slight_smile:
