When the approve email is delivered it has the three buttons: approve; open task and reject displayed at th bottom of the email ind to be able to green; grey and red respectively.

It would be good to be able change the colour, style, wording etc for these.

It would also be nice to be able to control the buttons separately - have just the open task, or just the approve and reject. And be separate them and place them and place the anywhere in the email.
