I only just downloaded the new beta of Windows Live Writer today. I’ve been using this gem of a program for the last few years, and it just gets better and better. The UI is ever so slightly improved (especially the toolbars) but other than that it is essentially the same awesome program its always been.
By the way I’ve finally started using the hot keys (I can’t remember if they were there previously – probably):
F2 will show/hide the properties form
F9 will show/hide sidebar
