Describe the feature you'd like

A way to zoom in diagrams or have them fill the whole screen when clicked, simialr to what other wiki software does (such as cloudformation).

Describe the benefits this would bring to existing BookStack users

At the moment its difficult to zoom in diagrams - we can open them in a separate tab and zoom on the browser but this zooms all open tabs of the browser. Having a way to have larger views of the image of the diagram when clicked would allow us to more easily read the diagram and thus make diagrams even more useful.

Can the goal of this request already be achieved via other means?

Not sure how it can be done unless zooming for the whole browser set of tabs which makes the rest of the fonts very large to view a larger diagram

Have you searched for an existing open/closed issue?

  • I have searched for existing issues and none cover my fundamental request

How long have you been using BookStack?

1 to 5 years

Additional context

No response

Well drawio images are just images when rendered. So this could maybe be folded into a more general enhancement to viewing images.

@kdamianakis second this, would improve user experience.

Just started using BookStack, found this to be a limitation writing the first article.
