Upfront Element Questions

I would like to commend you guys for the work on the new upfront 1.0. I loooove the padding feature as well as how intuitive the drag and drop now is.

I do have some questions on some of the Draggable elements.

IMAGE GALLERY
• How do I make the gallery full width?
• Specify how many images in a row?

POST SETTINGS
• How do I make it to show two columns?
• I also would like to style that section differently ( see attachment )
• Change the number of words/characters that will display as an excerpt.

If these can all be done in the front end and not through a CSS editor would be great.

Thank you and keep up the great work!
