Screenshots for non-image files

[Shinx]

Users should be given the option to upload one or more screenshots for non-image files, and these files should also have a clearly visible download button. Also, the word Displayed should be changed to Downloads for these files to make things more clear.

This part is available today via the 'Custom Thumbnail' Plugin - allowing you to add a thumbnail image to display for a non-image file.

If this feature won't get to the core code, it's quite easy to create a plugin for it.

the word Displayed should be changed to Downloads for these files to make things more clear.

At which location is it displayed and should be changed in your opinion?
