Amazed by people’s creativity . Thank you Lockal. Here is a user script to make feedly more useful for people who need a list view with full width .

You can get this userscripts from:
http://userscripts.org/scripts/show/162237

What it does:

• Makes layout a little more compact, less free space
• Full width of screen to display more content
• NO MORE YELLING AT YOU CAPITALIZED TEXT EVERYWHERE
• Grey colour title for read article when it is opened
• Mark categories with unread articles with bold
• Favicons are always shown
• Some visual fixes (e. g. misplaced images and youtube videos in RSS feeds)
• Arial Font to make webpages more responsive
• “shift+a” marks all as read

Note:
On Feedly need to use the ‘Modern Gray’ Theme and ‘Titles’ View.
