The ease of use, how user friendly it is for my team to be able understand what I am looking at when we are managing our assets from one platform! It would help if you could have more icons available as well so that there was not always something missing or needing explaining - but this also depends upon your users' knowledge level too which can vary greatly between businesses/companies (which may mean some people will need an explanation while others won't). As mentioned above though its very easy with little training required by anyone who knows nothing about Excel spreadsheets etc., however understanding all aspects such things does take time & effort especially being used daily within different departments across multiple sites / countries where each department has their own way they like doing certain tasks e..g uploading files into SharePoint library vs using File Manager rather than having both options open together side-by.-.
