When you right click / Crtl + Click the worksheet the option Recalculate is in the drop down menu, saves some clicking through menus.
When adding lighting devices in a plot. Vectorworks assumes you want to be using these devices for ambient lighting. It would be great to have a tick box in the "Set Lighting Options" window to disable this. I find myself very often in a situation where I would (in Open GL) need to see the physical presence of the devices but need my lighting settings to default. Bringing up the ambient lighting does not always work here since you're views get over exposured very easily here. Especially when publishing Open GL rendered viewports.
