I like the first steps in Premiere for mobile. Lots of features missing and a shame it's not up to Rush feature level yet.
One of the big features for me is to be able to store a project and associated clips in the Cloud (Adobe or even better my choice of service). That would allow multi device editing and ultimate flexibility.
Even better would be the option to then view the Premiere project in Express and bring that in like other assets. Tightening the workflow between Premiere and Express for on-the-go content creation would be fabulous.
Im sure you've already thought about this or hopefully are even working on it. Just my vote for this option.
