FEATURE: Display confirmation dialog when clicking on links from source documents

[tillprochaska]

Is your feature request related to a problem? Please describe. We currently render links in email and HTML previews. Clicking on links from source documents can be potentially unsafe or notify authors.

Describe the solution you'd like We should display a confirmation popup informing users about the risks of opening links from source documents.

Describe alternatives you've considered Alternatively, we could not render a clickable link and instead display the target URL in parenthesis after the link label so users have to actively copy and paste the URL.
