Dataset preview
We used to have this, we should bring it back. The big issue is finding a way to integrate it into the UI in an intuitive way.
Should be flexible concerning file type, e.g. show CSV rows, an image preview, an interactive network graph, etc, depending on the file type.
Also: the CSV preview could maybe have a quick filter/sorting feature? Though it should then also be clear to the user that they're (potentially) only working with part of the dataset...
Does not seem super necessary to me. I see the preview feature more as a way to get a quick glance of the columns and values. Sorting is already possible in the Explorer and after downloading the files. And, indeed, it could give the wrong impression that it handles all data.
Done for the most obvious file types, and it's easy to add new ones.
