Group movement shortcut key is set to CTRL+D but it does not work - normal movement (D) does work.

I have auto-pinning of planets enabled but it does not seem to work when I explore a new planet.....

Also, I recall from the beta there being some empire tree 'grouping' icons at the top left that I found very useful.. they seem to be gone now

Is there any way of bringing them back? I liked being able to set it up such that the only planets that would be shown on the empire tree were the ones that had my ships in it.
