I've posted a few entries using this tool now and I'm pretty impressed. It imported my blog template from Blogger and so I can edit my posts in an almost perfect WYSIWYG style (down to the default fonts and colours used on the page).
One thing though.... I can't find a way to minimise it to my System Tray. So I have to keep on relaunching it whenever I want to make a post.
Anyone know how to fix this?
