Site Origin Call to action and Features widgets

Hi,

In this widget, I see that I can not add text: Title and subtitle only.
As can I do to change the subtitle (h5) by simple text? (exemple in the link, below)

Another question:
Why I can not add a background image in this widget? To create a call to action is sometimes interesting place a text related to the image.

I leave a link to the page where you can see this questions.

Also I have a problem with the “Features” widget:

According to Google Page Speed Insights, in the mobile version, the screen width is too large, it does not fit. Why is this happening? The other widgets (in the same page) fit perfectly on the screen.

You can see too in the same link.
Thank you very much!
