Hi - I tried your plugin with WordPress 3.6.
There was the following warning when I activated it:
The plugin generated 16 characters of unexpected output during activation. If you notice "headers already sent" messages, problems with syndication feeds, or other issues, try deactivating or removing this plugin.
Also, I could not access media with the plugin installed.
Lastly, when Jetpack is also activated, the widget cannot be configured.
I will try another plugin to suit my needs.
