Enabling accessible drag and drop
-> Using the context menu, and a new two stage system, this allows
users to curate icons and widgets on the workspace
-> Move icons / widgets to any empty cell on any existing screen, or
create a new screen (appended to the right, as with regular drag
and drop)
-> Move icons into existing folders
-> Create folders by moving an icon onto another icon
-> Also added confirmations for these and some existing accessibility actions
Limitations:
-> Currently, no support for drag and drop in folders
-> Considering moving the drag view so it doesn't occlude any
content (in particular, when user changes pages)
-> In this mode, accessibility framework seems to have
problems with the next / prev operations
