The editor is disappointingly basic

Im only a day into using MarsEdit, but I am struggling to get some basic formatting when adding images. For example, with a floating image, to enable some padding space between the text that flows next to the image. Looks like I have to tweak it in raw HTML.
The program is stable and reliable, connects easily to Wordpress. The email inbox look and feel makes it easy to manage entries.
