Where did object preview in baked map and mesh renderer sorting layers go?

Back in previous betas I was thrilled to see that the GI - Baked and other lightmapping preview options in the scene view provided a preview window that highlights the currently selected object's UV coordinates in the current previewed map, but now it's completely gone!
This has been a trend lately in Unity by stripping various editor goodies that took ages to implement for no reason, like the mesh renderer sorting layers overwriting dx/ogl default z ordering which is very important option at least for some of us to integrate more 2.5D workflows.
Also the minimum seperation slicing distance in the 2D editor and many more.
Please UT do something about it and stop taking away featues. the editor is barebones enough we need more options and windows not less.
