Please make a way to sync smart collections between devices. Even Apple has a robust way to sync smart albums (or smart playlists in iTuns for that matter). It's the only feature holding me back from taking an iPad with me while traveling instead of my heavy Macbook Pro.
for me it would be a great advantage to have a synchronization since most of my collection are "smart" due to locations, dates, tags, ... and why can a company like Adobe not solve what a plugin can? Regards
