Right now I’m using [WP Editor](http://wordpress.org/extend/plugins/wp-editor/screenshots/ “WP Editor”).
I’ve had a few problems with the plugin where I try and click somewhere to edit, and the cursor either stays at the front of the line, or it maybe go in about 10-15 characters.
So I’m looking for a better one. I might try TinyMCE again. But I’d still like to have the format highlighting that WP Editor does.
