few suggestions

it should have "bake all " option to bake everything

another one is "bake from view"
which is little tricky , here are the steps to make it possible

1- add new uv to object ( Project From View) and name it "View UV"
2- render out scene
3 - save rendered image temporary at some location
4 - add that saved image as diffuse texture in ypanel and set its uv to our newly created uv (ViewUV")and set material to shadeless
5- now select first uv layout from uv map panel in property window
6 - go to edit mode of our object and add new image and name it 'bake_from_view" in uv editor
7 - now go to bake setting and select "full render" and press bake
8- add newly baked image to ypanel (bake_from_view)
9- delete uv layout (VIew UV)

this way we can get Bake from VIew option , sometimes its really useful , because full render bake mostly dont give same result as we can see it in rendered output , it will be useful in many ways

I already add option to bake full render. The baking from view is kind of complicated to implement, so I can't promise you when I'll implement that feature.
