SUMMARY

Allow the user to define what metadata should be displayed (comments, file name, tags, etc.) as an image overlay in `Preview` mode.

STEPS TO REPRODUCE

1. Open image in Preview mode

OBSERVED RESULT

No metadata are displayed.

EXPECTED RESULT

Comments of all lang variants, assigned tags, ratings, color lables, file size etc. should be displayable.

(Similar display options as of // Settings // Configure digiKam // Views // Icons should be available for Preview.)

RATIONALE

While adding/reviewing image metadata (tags, comments, face tags) in Preview mode it is rather slow to identify what user metadata are already filled in.

I.e. I have to switch the side panels to Tags (check "Tags already assigned"), to Description (open the language code to see which lang variants are already filled in), etc.

It is possible to increase the icon (thumbnail) size in "Thumbnails" mode to somewhat emulate a Preview mode, however:

- the size is limited

- the image quality is not the same as preview

- it is not possible to add face tags.
