I was just writing a similar feature request. I’ll post here my inputs:

Enhance File Preview experience for Attached Documents and Media

Current Situation:

When viewing attached files (images, PDFs, etc.) in the Mac app, the current behavior disrupts workflow continuity. Opening an attachment creates a new tab, and upon closing it, the app doesn’t return to the original context. Instead, it shows the last opened tab, causing users to lose their place and requiring additional navigation steps.

Impact on Workflow:

  • Frequent context switching disrupts concentration
  • Extra time spent navigating back to the original entity
  • Reduced efficiency in collaborative workflows where document review is common
  • Increased cognitive load from managing multiple tabs

Proposed Solutions:

1. Modal Preview:

  • Implement an overlay preview window for attached files
  • Preview remains contextually connected to the source entity
  • Quick access to view and dismiss without losing context
  • Support for common file types (images, PDFs, videos, audio)

2. Two-Panel Preview:

  • Split-screen view showing the entity and attachment simultaneously
  • Maintains context while reviewing attached files
  • Allows for side-by-side reference and comparison
  • Flexible layout for different file types

Benefits:

  • Streamlined workflow with reduced context switching
  • Improved collaboration efficiency
  • Better user experience for document-heavy workflows
  • Reduced time spent on navigation

  • ClickUp also has a simular quick preview.

  • Even Fibery already has something like this for attached images inside comments:
