As part of patch 1.2.223, we are merging the dashboard and spring-cleaning pages to simplify the organization of sources. Here is what it likes:
The sources highlighted in blue are the ones your share the most. The ones in red are the ones you have not read for the last 30 days. You can easily delete sources, mark them as favorite and move them using drag and drop.
You should expect to see more in this area in the next 10 days including the ability to order categories on the navigation bar as well as rename categories. If you get a chance to play with it please let @feedly know what else you would like to see added.
