I have to say, this plugin is exactly what I needed for a recent project. I love this plugin, and have recommended it to many.
That being said, I had a couple ideas to make it even better.
1) TinyMCE option for the editor
It would be great to have the option of editing content in this field using tinyMCE, rather than just plain text.
2) Option for editor field to be open, rather than collapsed.
A few of my workmates have had to ask me where they edit the sidebar content, because they didn't notice the editor for it. I feel it would be more intuitive if the editor was expanded open by default.
That's all I can think of for now. These 2 tweaks would make this plugin perfect.
Thanks again for your hard work.
