As you might know, the guys on Elitist Jerks are working on a new spreadsheet called ShadowCraft. So far it's just been code without any interface, which is pretty hard to handle for non-programmers. However Caffeine on Elitist Jerks (original post) recently created a very simple interface for it where you can input gear and change some settings. It's not much but it will certainly be nice to have around until the real deal is done.
To make it clear, this does actually use the ShadowCraft code created by the top theroycrafters such as Aldriana, so it should be accurate. But it's a very primitive interface. It includes gear selection, buff settings and reforging but not armory import, specific talent choices etc.
