However, if you really want Lightread to feel at home on your elementary desktop, you may consider changing its theme.
Ćukasz Rejmer created a stunning elementary theme.
To install, download the .css file below and drag or paste the file into sudo apt-get update
sudo apt-get install lightread
/opt/extras.ubuntu.com/lightread/share/lightread/media/app/css/
For those of you who don't know how to modify root folders, again paste the following into the terminal to gain root access:
gksudo pantheon-files
Did I mention there's also messaging menu integration?
Give it a shot, and add elementaryupdate to your feeds while you're at it!
