Individual thumb preview images for CHM files?

Help & Support

Hi!

PDF document files can each have a different individual preview image in the thumbnail view:

But CHM document files look all the same in the thumbnail view:

Would it be possible to add a custom preview image to each individual CHM document file (with a specific tool)? This would be very useful, so CHM files could also be distinguished visually.

It's not Opus that generates the PDF thumbnails, it's (most likely) whatever you have installed for viewing them. If a third-party CHM viewer exists then this would probably work in Opus automatically, although I can't say I've ever seen one. CHM as a file format is mostly deprecated these days I believe.
