The customer should be able to customize the entire solution to their own color schemes, fonts, images (further than system standard) to give a more personal feel to D365 as a whole. Although a Microsoft D365 product, it would give the customer the impression that they truly 'own' the product rather than a 'generic' feel. D365 has improved on this massively from 2012, but taking this to the next level could really draw the customer in. Making them feel like its 'theirs' and not a "3rd Party" system would be a great selling point. A simple idea, but a 'WOW' factor for presales.
