It's a nice feature to have in the admin area. I'd like it a lot if it could be extended with some features:
- Please make this plugin translatable.
- Don't put the data into a separate table (we are struggling to keeping the number of tables at the minimum necessary), an option saved in the _options table would be enough.
- If the edition/reading of the pad could be adjusted according to the WP roles, it would be even more useful since not only admins could use it.
Would you like help with the development of the plugin? I'm just a beginning developer, just made a few site-specific plugins for several networks/sites, a hand to learn the necessary subversion to help you would be very appreciated and I've could develop some of the features I'm proposing, if you want to.
