Adjust text size and background

Hi all,

I’ve got 3 questions.

In the free version:

1) Is it possible to change the size of the text in the pop-ups
2) Is it possible to adjust the dark background behind the pop-up?
3) Is it possible to set the position of the pop-ups? Sometimes you need to scroll after opening the pop-up to have it in the center of your screen.

Thanks!

Best, Roosmarie
