First off, thank you for a great and very helpful plugin.
Following the instructions in your README I tried to disable the statusbox ("Post Information"). But the theme's functions.php loads too late in the page-init sequence for an add_filter() call to work.
I was able to work around this by hacking your source code directly, which is fine for me but obviously not ideal. Please consider adding these as checkbox toggles in the Settings / configuration of the plugin. Thank you!
