UVing Point Merging

Heya folks, so worked out a ton of things about UVinga few thing i cant get to grips with is the sceme system an the section systems, for example in Maya if i select an object it will stay live in the UV tab an let me see my mesh (Not have an orange box around it)

And B, if i select a point in the UV it selects it in the Othergraphic view so i can easily dissern were the point is on the mesh and when merged with another point native too it will make the scheme dissapear? Is any of that possible in the native UVing or do i need a add on.

Imagine for context

As you can see iv manually merged it into a easily to pack form but need too unwrap it with the new schemes iv made in the UV view rather then the ones in the orthographic.
