When I'm on the GCode Viewer page I can see what layer number I'm currently viewing. If set to sync to job progress this always shows the currently printing layer. Super!
But I can't find the number of total layers to be printed. This is IMHO good to know, for example to easily see how many layers there are still to go when getting closer to the end of the job. If each layer takes 10 minutes it's super nice if I could eaily see if there are 2 or 3 layers to go. Sort of 
If this has already been discussed or even worse, the info IS on the page and I've just missed it 
Then sorry.
