yes, in metadata, there are a lots of duplicate data. But it's Exif
standard (and non standard as Makernotes). It's a mess legacy from photo
history...

Use Metadata/Display fileter from setup to only display what you want. On
top of metadata viewer, you have buttons to switch in filter view or not.

yes. It's data resume for non technical photographers.

yes i see this problem too using a 4K screen. We will take a look to fix it.

this info is already in the list displayed, if this is found on metadata

This also displayed into digiKam properties section from this view.

Look the active filter settings on the top of metadata viewer.
