Let me rephrase it. :) I like it because it's faster but visual cue will be very helpful. :) It could be word Preview next to 'Category' field. Something like Preview.


Also, I got an empty frame after the message:
---------------------------
Microsoft Internet Explorer
---------------------------
For the FONT tag, only the SIZE, COLOR and FACE attributes are supported. This is in regards to the Message field.
---------------------------
OK
---------------------------

It didn't bring me back to the message edit window.

BTW, I almost lost this reply because I thought that it was posted but it still in preview. The different background for preview would be definetely better.
