I can finally play a little with MarsEdit. It has been sitting in my downloads folder for a few days, now I finally found the time. I was able to set it up quickly and easily, I can see the last posts I wrote in Radio and my categories. Hitting the "Post" button will send this words to my weblog, cool

The application is nice and elegant, like all Ranchero apps.

Unless I'm missing something, there's no WYSIWYG editing. There are tools to help me write html tags, there's a nice html preview, but no WYSIWYG.

Brent is a very smart person, there probably is one or more very good reasons for lack of WYSIWYG editing in his product. Maybe Ranchero users simply don't care, maybe it will appear sometime in the future.

The more I'm using MarsEdit, the more I'm liking it. Writing in a real app is waaay better than writing in a browser!

This brings me to another question: will there be a way to extend these applications?

If editing is done in browsers extending UIs and features is relatively simple. For example we have developed tools to allow users to add ENT data in their posts using Radio, Manila and MovableType. ENT is a little thing, there are many emerging types of microcontent and there will be the need to edit them somehow.

What about some kind of plug-in architecture to allow developers and users to extend tools feature sets? Are current API extensible enough to allow such features?
