Do not make the mistake of thinking that because my conclusion is the same as another person's that my reasoning is the same
Taking a deep breath…
First the bad news. Because I used a relational shotgun to handle my mosquito–sized storage needs here, the first version of MTClient, zipped into an archive with a single subdirectory, weighs in at a hefty 3.1 megs. There's a chance that version 1.0 can come in at less than a meg. To compensate for that, you uninstall it by deleting the directory. I just noticed the spell checker leaves an entry in the Registry, but that will change.
Now, MTClient:
Anyone who's posted to a Movable Type blog should be able to figure out how to work this already. There are only two things I want to be specific about here: To set up a blog account, you click the Configure menu button and select Account Setup.
The other thing is, icons are mandatory, but not always clear, so:

Mouseover the toolbar buttons to see the hot keys that do the same stuff. Saving a post and the image tag builder aren't implemented yet, but you might not care.
Sounds cool. I don't really have a lot of need for a client of this nature since I'm usually always online when I'm at my computer, but I'm sure it will be useful for a lot of folks :-)
It certainly will.
It's not a blog maintenance tool, sis. It's a writer's tool. It's a pretty rudimentary HTML editor but tweaked for me, to make it easier with all the volume I generally produce, considered numerically or by length.
It correctly handles Microsoft extended ASCII characters that are cut and pasted into your post…those characters choke posting with every other client I know of, and even when pasted into MT's web interface they display poorly on non-Microsoft OSes.
All those tool bar buttons have hot keys so, for instance, you can highlight some text, hit Ctrl-Alt-A and build a hyperlink around it without mousing or hand-typing HTML.
And it's got spell checking. And a thesaurus (told ya it's for writers).
It will also provide the HTML for lists and tables, and the version under my fingers right now has a rather cool file upload capability. Within the limits of XML-RPC, you can upload any type of file and tell the wizard whether it's an image (in which case it produces an <img> tag) or a data file (in which case it produces an <a> tag).
