For those of you that missed @ChrisMullen demonstration of the new UX you can watch it here.
He'll take you through a quick page build by using the L1 model.
Super easy - great video - Love @ChrisMullen's style. Highly recommend it.
Indeed Chris was fab in his tutorial video.
However I still feel that New UX has got to do more in order to get the attention that it deserves. For example it lacks tons of features on Charts - need to bring more and more types of charts.
Look and feel needs to be better - Give users ability to change the background of the card.
Limitations on the number of cards per row (As of now it is 4) - Has to have some technical reason behind it
Ability for users to input a text message on KPI or Chart cards directly
Open source module feature will be highly beneficial
Multiple Drill Down feature (as of now it is single drill down)
Rearranging the pages
Many many I can think of but let's just stop here:)
