An update made by Canonical has changed the way shortcuts are opened in Unity
Canonical is trying out some new features with Unity, in Ubuntu 13.10 (Saucy Salamander), but one of the latest updates have left users wondering about the validity of those choices.Besides implementing the 101 Scopes project in Ubuntu 13.10 (Saucy Salamander), Canonical has also enabled double click for all the shortcuts in Unity.
Until now, left-clicking on a shortcut in Unity's Dash would open that specific application. A right click would open a preview of that app, with a short description, and some contextual options (such as uninstall).
With said modifications in place, left-clicking and right-clicking now serve the same purpose, to open a preview of that window.
Users now have to double click any shortcut in order to open that specific application. Also, there is no feedback that informs the user if the double-click has been done correctly.
The only possible reason for this Ubuntu 13.10 update is to show the users about the preview function, which could have been mostly unused in the past.
Whether this “feature” will remain in place is a mystery, but there is plenty of time for Canonical to return the previous settings.
