EVA Build on planet/moon surfaces not very practical

[djr5899]

Had my first attempt at trying to do an EVA build on a planet.  It did not go well.  AT. ALL.  2 big things I noticed:

• Toggle snap does not appear to work.  By default, snap is off (shows the circle) but building still "snaps."  This is even more noticeable when attempting to have the Engineer use the Move Tool to adjust a part location.  Whether the circle or the hexagon is showing, it is attempting to snap to parts when building or adjusting.
• Parts are not attaching correctly.  I've trying to build a simple rover.  I've placed a Rovemate down, and I am trying to attach an M1-F wheel to start building a rover.  The wheel always attaches at an incredibly odd angle no matter where you try to place it.  Then when you click build, it tries to attach it differently (like it tries to correct and attach flat).  Further, 50% of the time when I attach a wheel, it corrects the position and sends the attached wheel and Rovemate flying through the air.  You can see in my screenshot below as my Rovemate with 2 wheels attached goes flying by the distant sun.

I don't see any specific bugs opened for this, but, this just seems like maybe EVA Build on planet surfaces needs another look.  Maybe its just me, but it's not very practical or useable in the current form.  I think the big thing is, when you place a root part in VAB/SPH, the part is initially placed above the surface and stays there.  When doing EVA Build on a planet, the part stays a few meters off the ground for about 2 seconds, and then falls to the surface.  Maybe a way to make the root part only hover above the ground until the user exits EVA Build mode?
