Hi. I know that you are improving the html editor, Last time I tried Latest development version: 0.8b3 , I could not navigate with the arrow keys in the html editor.
I have two suggestions. Replace the html editor with notepad++ and instead of the site manager link direct to filezilla.
But everything else is great. I like the interface and the ease of styling.
I really like KompoZer. I would be great, if you could talk with the authors of the software above, and maybe get them involved in the KompoZer project.
