MarsEdit is another Brent Simmons creation from Ranchero Software.

Best startup dialogues so far. Let's do the picture thing. Hm, can't drop a picture in. Ah, you have to pull down the "HTML Tags" dialogue and it gives you a little well to drop the picture in. There are some useful options.

The editing interface is tags-visible, OK by me. Category selection seems to work well.

I pasted in a big screen-shot of the editing interface and that seemed to pretty well screw up my whole Roller blog. Removed it. Urgh. The stupid clouds picture shows up fine in Firefox, but twice in Safari.

Ah, it's just a Safari bug, when you widen the window the image stabilizes.
