Text input field combined with other elements

For my clients it's difficult to use the text editor on there mobile phones. A solution is to use the function to automatically open the text window.

The problem with this solution is that my clients can't find the fonts and color tools because they don't understand that they can press back to go to the other window.

It would be nice if the text input field could be displayed on top of the other tools i added a screenshot from how it would like to have it.

If this can not be added into the plugin itself does somebody know how to set up the javascript the correct way to do so, i know how to change the html and css but changing the javascript is a little to difficult for me.
