I have an ExpressionEngine website built for a client, and the entire content is built inside a template.
I need to allow the client to make modifications, but I don't want the source to be visible by default.
All plugins only work with channel content, not with the Template Manager.
EDIT #1: Found this, but it's for EE 1.x, and it needs to be updated for 2.x - http://ellislab.com/forums/viewthread/56223/
The ideal solution would be injecting a RTE editor to convert the Template Manager textarea into a visual editor.
