Hi,
Yes, this is something that we can improve to the V-ray 3.0 UI. It will be considered with our developers.
Meanwhile you can create a default 3ds max start up file using the following steps:
*) open 3ds max
*) open V-ray render settings
*) right click on the UI mode (Basic) and choose Switch all to expert
*) save this scene as maxstart.max to your default scenes folder
You can go to Customize\Configure User Paths to figure out where your scenes folder is pointed to.
