I'm making another attempt at using the new email builder and a few things I'm running into are:
- Adjusting padding for the width of the entire email ( I can't get rid of a very wide margin). I'd like our top banner image to fill the whole width of the viewport.

- Center buttons and the option to make the button width 100%.
- There is a lot of space between images and captions. I'd like to make adjustments there.
Are there any workarounds (besides using the HTML editor)? I'd also like to know if there have been any updates recently that I'm missing.
