I really like the idea behind your plugin. It's a great alternative when you want to give some access to clients without installing the whole Static Page plugin.
However, I have several question, that can become feature request if the answer is no ^^ :
- Does it support multilanguage using Rainlab Translate plugin ?
- Is it possible to create an option to disable access to the "tab" and "php code" parts of the CMS page (to let the customer just edit your custom fields ?)
