When drawing shapes, e.g. box, how can I get it to snap to the grid or edge/vertex? A hotkey would be ideal
I see the menu option for ruler/annotation. I can't find anything for shape drawing.
I think it's down in Edit>Options?
I'm aware that currently there is little feedback. But if you want you can try the next major version's preview (representing the master branch and continuously updated): https://www.klayout.org/downloads/master/ This version has better visual feedback and I also think snapping works somewhat better.
