Cannot Focus on Component While Placing Part in VAB

[Washed and Rusty]

If a component is selected so it can be placed, MMB can no longer be used to center a view on a component. Part selection has to be canceled so to use MMB for centering, then part reselected. This is inconvenient because the first thing that comes to my mind is that I need X component on my ship, so I select it. It's not until after that I begin to think about where exactly I'm going to place it. As far as I can tell, MMB serves no other function while placing a part. If it does serve a function I'm unaware of, having it be MMB doesn't work out well. Allowing MMB for focusing while placing a part would make building more seamless and enjoyable.

100% agree, I have tried using the MMB multiple times for this purpose while holding a part.

My opinion is that Wasd or arrows should move and rotate camera. So many times i naturally click them at editor and nothing happens. 

It could be nice to be able to hide some parts which prevents seeing stuff behind them.
