As you can see in this thread, most of my replies came within 30 minutes but that’s not always going to be the case.
Your patience is appreciated.
Also, we will not be able to help to achieve the exact look you are going for. Our support is here to point you in the right direction and provide some easy custom CSS if it’s simple enough.
Thanks for your understanding.
