Reddit Lens

As described by a post on WebUpd8:

A Reddit user has created a cool Unity Lens for Reddit (a website where you can find what's new and popular on the web with a very active Linux section). By default it displays /r/linux, /r/ubuntu, /r/iama and of course, the main stories.

The search field for the Unity Reddit Lens is basically a filter for Reddit categories so if for instance you want to see the top stories in the /r/technology category, search for "technology"...

Answer 17

Pirate Bay Scope & Torrent Lens

The technology itself is perfectly legal, but it has been debated if its implementation in connection with copyrighted material or otherwise illegal material makes the issuer of the bittorrent file, as opposed to the copyrighted material itself, liable as an accomplice or infringer.

Answer 19

Unity Bliss Lens

This lens puts applications into category folders in the dash, similar to the old GNOME 2 Applications menu categories.

According to Mikkel Kamstrup Erlandsen (the lens' creator) from this OMG! Ubuntu article:

“This is a very simple implementation of an apps lens for Unity. It can be used as a replacement for the default apps lens if you want something simpler, or it can be used as a solid starting point for writing your own lens.

Bliss is by no means official or anything. It is a quick hack to showcase how you can go about this, mostly intended for developers who want to do their own thing. That is also why you wont find a PPA for it (not from me at least)”

Instructions for installation:

1. Download the package from https://launchpad.net/unity-lens-bliss by clicking the green button on the right side of the page.
2. Extract the package into your home folder.

3. Run the following in a terminal:

   cd unity-lens-bliss-0.1.3
   ./configure –prefix=/usr –sysconfdir=/etc
   make
   sudo make install
   

4. Log out and back in to see it in the Dash.

Answer 20

Spotify scope

Spotify scope adds extra resources to Ubuntu's default Unity Music lens, displaying Spotify songs when a particular item is searched.

Spotify scope depends on spotify-client-qt, tool that must be installed before the scope.

A definitely interesting innovation about the above mentioned scope is the marking of its items, meaning one can easily differentiate between songs provided by Banshee and Spotify's, the latter featuring a Spotify symbolic icons.

The usage is simple, properly oriented towards its corespondent application, meaning, playing a Spotify song is as simple as clicking on it (the item will be opened via the Spotify client).

Install

First, install the Spotify client (download the package and install it via Ubuntu Software Center).

   sudo add-apt-repository ppa:scopes-packagers/ppa
   sudo apt-get update
   sudo apt-get install unity-scope-spotify

Active the scope by logging out and then logging back in.
