I feel that wordpress dashboard should be separated in to two parts and those regarding CONTENT ( posts, terms, links, comments etc ) should be their in front end and for configuring themes, plugins, settings etc could be in wp-admin. I can sense a better usability when iam using TUMBLR ( for posting content ) than in wordpress. The percentage of users using wordpress for posting content is higher than developers like us, for them their is no need to show the admin panel.
A simple use case,
why should i see plugins/themes/settings , when my priority is only posting content.
I also fear that Tumblr could overtake wordpress.com because of these problems. we know many people are using wordpress, but i feel their are many more yet to find it.
Hope people in wp would consider.
