The admin panel of devicedesks allows you to create new pages or adjust existing ones without any technical knowledge required! I can't imagine working with something else in my life time again!! It's just great.
Nothing as such but i would say that some features are not available yet which have been requested by users like integration between different platforms (mobile phone app) etc.. Also it could be better if they add more payment options other than credit cards so user does get multiple choices at once instead only one option from card provider!! And also there should definitely come up automatic notifications when someone logs into your website using mobile apps even though he/she has logged out before logging back onto desktop version!
