Metadata panel: Show more metadata before going into details

[bprusinowski]

I feel like it'd be interesting to have the dimension values or for example the min/max as a gray text under the dimension name in the panel describing all the dimensions (so that you do not have to open the panel in most cases, and also to give a taste to the user of what she will find in the details). This is not for the PR, but something to keep in mind. @AnninaWalker
