Courtney,
Because this is in the app these isn't much you can change about the control's behavior except to uncheck that it is a rick text field. But obviously that will remove the capability you need. For my forms that use rich text I have the box wider so the tool box is on two lines and taller to show more lines of editable text. This tool bar is in a table-row table-data with a class of k-editor-toolbar-wrap. So even using CSS, you will only be able to move it around some but not to the ribbon which would be preferred.
But maybe this is of some help. You can select the tabledata that holds the tool bar and hide it with the following. Just go to form or layout settings and put this in the Custom Javascript box.
NWF$(document).ready(function(){
NWF$(".k-editor-toolbar-wrap").hide();
} );
Now the trick is to find the appropriate function to make it visible again. Maybe moving it to the left is easier with CSS so that it is always there? or when you click in the box you then show it. Since these textareas use iframes, it will be tricky to catch an onfocus or click event.
