The ability to swipe a folder icon and open the first icon in a folder is absolutely brilliant!
This could be taken one step further by adding an action for each swipe direction (up, down, left, right).
That would allow up to four different apps to be opened in a single movement using only one icon!
Suggest a special 'Icon Appearance' be applied with arrows ↑↓←→ to the Icon Shape to denote that multiple swipe actions are available.
