Dash - Drag and drop app install from App Lens to Launcher is broken

[John Lea]

When in the App Lens (and Dash home) results view and previews, the user should be able to drag and drop application icons to the Launcher to install the application. This same interaction should also be triggered when a user clicks on a 'Available for download' application.

Desired solution:

- dragging and dropping a application from the 'Apps available to download category header' onto the Launcher should:

1) add the application icon to the launcher in a grayed out state
2) install the application.

As the application is installed, the app icon should fill with colour. When installation is complete, the icon should be in its normal state fully filled with colour. Remember to also review bug https://bugs.launchpad.net/unity-design/+bug/676453 for details of the installing animation.

===============================

This bug would be an ideal bug for someone to get started hacking on Unity, here's some information:

 * Time to fix: 10h
 * Difficulty: normal
 * Implementation:

This bug should piggy back on the implementation of https://bugs.launchpad.net/ayatana-design/+bug/676453 using the same internal call structure, but setting up the apt-daemon install process by itself. It's not unimaginable to consider even having the dash use the same interface for installing as the software center (making the same dbus call as mention in bug #676453)

 * Where to look: src/Launcher.cpp
 * Workflow information: http://unity.ubuntu.com/getinvolved/

Does not seem fixed using unity 4.14.2 here.

When searching from the dash for example "Skype" and is not installed I don't get the recommendations to install it from the "apps available for download" in the home/main lens. I only get an empty search.

But when I do the same in the Apps-lens you do get the recommendations.

Searching directly from the home lens makes this functionality more discoverable and is a great alternative to using the terminal and apt-get on slower computers and not have to always wait for USC to open (unless you want to read more info.)

Should another bug be open for this or is already in the plans to add this functionality to the main/home lens?

It would also be preferable not to show the "apps available for download" in the home-lens by default, but only on Searches since the recommendations become more relevant and much better than getting no results.
